Ansible: install package only if is the newest version - regex

Introduction: The objetive is to install and configure a package into a on premise server (without internet connection).
I already achieved a task to install using a .deb file and the apt module, and also configure the service using the lineinfile module to edit the package configuration files.
The problem: if the server already has an old version!
I'm able to get the current version installed using the command:
dpkg-query -f '${Version}' -W packageName`
and I also developed an regex to get the number to compare.
But now I'm stuck! =/
Question:
How can I use the regex to compare the current version number with the version number to be installed?
I already read the filter documentation, but it did not rang any bells. >.<
Uninstall and install is also an option but it doesn't seems the right one.

I cannot post a comment due to <50 rep at this point so I'll try to elaborate as much as I can. I hope this does answer your question, please comment if not.
If the issue is with installing when an older version is already installed, you can use the "only_upgrade" option of the apt module:
shell: ansible-doc apt
- only_upgrade
Only upgrade a package if it is already installed.
[Default: no]
type: bool
version_added: 2.1
Then, when adding a register var to this action, you'll know if the packages was indeed upgraded, and assuming you need to push new config files due to version change, you have what you need.
The flow would be:
- name: Attempt upgrade first
apt:
deb: path/to/file.deb
only_upgrade: True
register: was_upgraded
- name: Install the package on a server that never had it
apt:
deb: path/to/file.deb
when: was_upgraded.false

redhat - using yum list available to query EL6, EL7, EL8 repos for specific package

Kinda new to redhat el and have inherited this machine. I have a redhat EL7 machine. I want to use yum list available to see what package version are available on EL6, El7, EL8. Since I have some packages that are from all those versions.
What repository do I have to add to see which version of packages are available in all those versions of redhat?
There is a package browser in the customer portal.
What problem are you trying to solve? There might be a better way than comparing package names and versions.

How to choose the right version of Google Cloud library components in python?

I have a specific version of google-cloud-core in my server and I don’t know how to choose the other libraries in a way to make them suit with my google cloud core version.
I can’t just move to the latest versions because old programs cannot run into new versions for example BigQuery library.
My specific need is to know « how to know » which version of Google Cloud Storage should I choose according to the 0.26.0 core version.
Is there some repositories where we can find packages grouped by google-cloud-core versions?
In my case the version 1.6 of google-cloud-storage works but I found it just by downgrade and try again method !
Best regards
What you can do as a workaround is create a virtual environment, install a specific library - like google-cloud-storage - and check the dependencies installed with that library version. I made a quick test and installed a few versions of google-cloud-storage. For version 1.3.0, the google-cloud-core 0.26.0 dependency was installed.
You can do so by following these steps:
virtualenv env-name
source env-name/bin/activate
pip freeze (to check there is nothing there)
pip install google-cloud-storage==1.3.0
pip freeze (again)
Once finished you’ll see google-cloud-core 0.26.0 was installed.

unknown error: call function result missing 'value' for Selenium Send Keys even after chromedriver upgrade

I am getting the below error while sending keys.
Result Message:
System.InvalidOperationException : unknown error: call function result missing 'value'
(Session info: chrome=65.0.3325.146)
(Driver info: chromedriver=2.33.506120 (e3e53437346286c0bc2d2dc9aa4915ba81d9023f),platform=Windows NT 10.0.14393 x86_64)
I have updated the chrome driver to 2.36 but still my code search for 2.33?
Any idea ?
I've gotten the same error, please download the last ChromeDriver version and/or update chrome browser version and it will be working fine :)
https://chromedriver.storage.googleapis.com/index.html?path=2.36/
After updating the Google Chrome browser to Version 65.0.3325.146 (Official Build) (64-bit), I'm also encountered with the same error
while sending values to the input field, here's the error message...
selenium.common.exceptions.WebDriverException: Message: unknown error: call function result missing 'value'
using Chromedriver 2.32 and Google Chrome 65.0
As I did some research on the same, I found a recent commit on Google chrome v65 changelogs which help me to resolve the issue.
Solution:
Update Google Chrome to latest stable version (in my case it's v65 on 9/mar/2018)
Download and configure latest chromedriver (v2.36).
For configuring chromedriver (on Ubuntu) follow these steps...
Extract the downloaded zip file.
Copy the extracted chromedriver file to /usr/local/bin or to the location where you usually store the executable binaries.
Add the same path (where you place the chromedriver file) to environment variable PATH as
export PATH=$PATH:/usr/local/bin
For testing the installation, restart the terminal and type this command
chromedriver --version
it would show the version of chromedriver that you just installed.
Note: If the chromedriver already installed and configured then just replace the existing driver file and If you don't know where the Chromedriver binaries already stored then try to find the file using following command
sudo find -H / -type f -iname chromedriver
It is because of the update of chrome browser version from 64.xx to 65.xx
Now you have 2 options to run your tests successfully.
Downgrade your chrome browser to previous version and with the old chromedriver which you have now.
Upgrade your Chromedriver to 2.36 version with the updated Chrome browser.
visit https://chromedriver.storage.googleapis.com/index.html?path=2.36 and download the new chromedriver.
Option 2 is better.
Replace your ChromeDriver.exe with latest version.. Same can be downloaded from Google easily.
Also its better to get it done automatically by using webDriver manager as explained below -
1. Add Mvn dependency to your project POM:
<dependency>
<groupId>io.github.bonigarcia</groupId>
<artifactId>webdrivermanager</artifactId>
<version>${webdrivermanager.version}</version>
<scope>test</scope>
</dependency>
Now in your Browser instantiation class instead of using traditional way to create driver i.e. by using System.setProperty(See belwo)...
System.setProperty("webdriver.chrome.driver","src/test/resources/drivers/chromedriver.exe");
Use below approach:
WebDriverManager.chromedriver().setup();
webDriver = new ChromeDriver(chromeOptions);
And that's all, you are done!
Use below links for your reference-
What is Browser Binary Manager how to use it for Selenium
or chkout git project for same-

Need to update chromedriver :
In console, run: chromedriver-update 2.36
The error says it all :
System.InvalidOperationException : unknown error: call function result missing 'value'
(Session info: chrome=65.0.3325.146)
(Driver info: chromedriver=2.33.506120
The error clearly complains about InvalidOperationException
Your main issue is the version compatibility between the binaries you are using as follows :
You are using chromedriver=2.33
Release Notes of chromedriver=2.33 clearly mentions the following :
Supports Chrome v60-62
You are using chrome=65.0
Release Notes of ChromeDriver v2.37 clearly mentions the following :
Supports Chrome v64-66
Your Selenium Client version is unknown to us.
So there is a clear mismatch between the ChromeDriver version (v2.33) and the Chrome Browser version (v65.0)
Solution
Upgrade Selenium to current levels Version 3.11.0.
Upgrade ChromeDriver to ChromeDriver v2.37 level.
Keep Chrome version in between Chrome v64.x-66.x levels. (as per ChromeDriver v2.37 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
If your base Web Browser/Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Browser/Web Client.
Execute your #Test.
If you are on Mac:
brew upgrade selenium-server-standalone
brew upgrade chromedriver
if the above two are not installed:
brew install selenium-server-standalone
brew install chromedriver
I'm running Protractor and have encountered the same issue.
The solution in my case was rather simple.
$ npm update protractor -g
$ webdriver-manager update
If you are on the latest stable Google Chrome (e.g. 67) I recommend to:
brew uninstall chromedriver
brew tap homebrew/cask
brew cask install chromedriver
These set of commands will uninstall your current chromedriver, check for updates and install the latest found (e.g. 2.40).
Use xpaths instead of class names to locate elements
After updating chrome and its drivers it didn't helped me at all!!
I don't know how much it makes sense but it worked for me when i replaced class name with xpath. This is the xpath , i used to automate sending whatsapp message using python.
driver.find_element_by_xpath('//*[#id="main"]/footer/div[1]/div[2]/div')
previously i Was Using
driver.find_element_by_class_name('Some class Name Here')
In my case the team I'm on points selenium to a specific chromedriver file we had. In order to get Selenium to use the updated chromedriver, I first installed it with brew and then created a symbolic link to point where Selenium looks for it:
brew install chromedriver
ln -s /usr/local/Cellar/chromedriver/2.36/bin/chromedriver /path/where/selenium/expects/chromedriver
On the chance this might be helpful to someone I needed an additional step:
I am on MacOS X. I did
brew upgrade chromedriver
bundle exec chromedriver-upgrade
I have the chromedriver-helper gem installed, but it is stashed and requires the "bundle exec" prefix or the shell can't find the command.
The above fixed my problem.
As mentioned by others, the latest chromedriver did the trick for me. In case you downloaded the driver manually and want to tell appium to use the new chromedriver you can do so by this command:
appium --chromedriver-executable /path/to/driver/chromedriver ....
I'm running Protractor (webdriver-manager) with Selenium in a Windows environment, and I had to do the following:
webdriver-manager update --versions.chrome="2.36" (This downloaded the new Chromedriver to the right path but didn't enable it in protractor.)
Edit %userprofile%\AppData\Roaming\npm\node_modules\protractor\config.json and changed the chromedriver value from 2.32 to 2.36.
Delete my old chromedriver_2.32.exe from %userprofile%\AppData\Roaming\npm\node_modules\protractor\selenium for good measure (not sure if that was required.)
Or:
When another Chromedriver update became needed, I was no longer able to update this way. A configuration setting still expected the old path and filename, and I couldn't figure out where to change that setting. So I just renamed the latest chromedriver to "chromedriver.exe" and stuck it in C:\Windows\system32 (which is always referenced by PATH). Crude, but effective.
If you're using gulp-protractor plugin, make sure to update it as well.
I don't know if you're still on this, but I was receiving a similar error. I had the latest version of chromedriver in my PATH and Google Chrome was updated. I run Python 3.6 on windows 10 x64 bit. What I was getting trying to select a value from a dropdown menu on a webpage. The weird thing was, it would select the dropdown value correctly and the page would be updated nicely, but I'd receive that stupid error anyway and my script would freeze. So I just made an exception error handler for it, because like I said it selected the dropdown value correctly, so I just wanted to bypass that dumb error message:
# select by value
try:
select.select_by_value('100')
except:
pass
hopefully someone finds this helpful.
The issue is because of mismatch in chromedriver and chrome browser version.
Below link specifies the versions of chromedriver supporting the chrome browser's version.

Drupal 8 - Commerce Module - BC math PHP extension not found

I'm trying to install the commerce module in Drupal 8 however I get the error 'BC math PHP extension not found'.
I've searched for this problem and tried different things such as editing the PHP.ini by adding 'bcmath.scale=2' however I still get the error message.
Any help would be appreciated, thanks.
Just install bcmath plugin for your php version with no need to (re)build php as mentioned on accepted answer
# get php version
php -v
# install bcmath based on your version lets assume php 7.1
# for ubuntu
sudo apt install php7.1-bcmath
# for centos
yum install bcmath
# restart apache
sudo systemctl restart apache2
Above problem appears when installing commerce or commerce kickstart using composer
Update 2020
Please refer to #GiorgosK's answer for installing bcmath via a package manager if you are using a distribution that provides a bcmath package for PHP. I will ask the OP in comments to update the recommended answer, since that solution is probably what most people need.
Three years ago when I answered this question, I suggested that you have to rebuild PHP to get bcmath. That was incorrect. I was using an older distribution of Debian/Ubuntu that provided bcmath as a statically linked extension in the core php package. I determined at the time (incorrectly) that bcmath was a core extension that had to be enabled at build-time (like SPL and PCRE).
For those trying to troubleshoot a missing bcmath extension (such as those building/installing PHP themselves or nevertheless encountering issues), I've corrected and updated my original answer below. It explains in detail how to troubleshoot a missing PHP extension.
Original Answer (Corrected)
The error message indicates that PHP wasn't built with bcmath support or can't find the installed extension. PHP extensions are either built into PHP directly or they are loaded from an external dynamic library file at runtime.
Since PHP obviously doesn't have the extension built-in, it can't find the external library file that provides bcmath. This file on POSIX platforms will be called bcmath.so and php_bcmath.dll on Windows.
Extension files are installed under a directory indicated by the extension_dir property in php.ini. To determine the value of this property, run the following command:
php -r 'echo ini_get("extension_dir").PHP_EOL;'
The default value for this property is configured when PHP is built and may vary from distribution-to-distribution.
Once you verify the extension file is installed in this location, you can then check to see if the extension is enabled in php.ini. You should see a line that enables the extension like so:
# POSIX platforms
extension=bcmath.so
# Windows
extension=php_bcmath.dll
For Linux distributions like Ubuntu/Debian that install extensions via the package manager, the format is somewhat different since Debian employs a distributed configuration. Typically the package manager installs everything correctly, but you can check to see if an ini file exists for bcmath under the corresponding conf.d directory. These small ini files are snippets imported into the larger php.ini file, and they are typically symlinked to /etc/phpX/mods-available, allowing modules to be initially enabled for all PHP SAPIs such as CLI, CGI, Apache Mod PHP, ETC. Make sure a symlink exists for the PHP SAPI you need to use.
To ensure your PHP is loading the extension, run phpinfo(); in a test page and search for bcmath. You can also more easily do this with the CLI using a command like:
$ php -i | grep -i bcmath
# Success output: BCMath support => enabled
# (Another command that works well for checking extensions)
$ php -m | grep -i bcmath
# Success output: bcmath
In order for the CLI to show accurate results, it must target the same php.ini file. If it doesn't, then use the -c option to temporarily point the CLI at the correct php.ini (i.e. the one being used by your Drupal site).
Add BC MATH extension for PHP 7.2
If you are getting this (https://prnt.sc/sehmd5) error then, run below command using vagrant ssh
Run these command in root of vagrant ssh
sudo add-apt-repository ppa:ondrej/php
sudo apt update
sudo apt install php7.2-bcmath
service apache2 restart
Then open php.ini and search for bcmath
If bcmath scale is 0, Change it to 2
Restart php
Restart Apache
Hard Reload website
Install required modules
Similarly for any version of PHP, you only need to change PHP version in 3rd command.

Packages of OPAM remote can be searched but not installed

I've set up a custom OPAM repository, for the needs of the company I'm working for.
It can be accessed through SSH.
Here is the command I used to add the remote :
opam remote add company-repo ssh://git#host:port/repo.git
I get the following error when trying to install my packages:
$ opam install <package>
Your request can't be satisfied:
- No package matches <package>.
No solution found, exiting
This is awkward because I can see them using opam search ....
Am I missing something in the process?
EDIT
I can install my packages properly on my dev environment, using opam pin. I only have the problem with the production repository.
EDIT 2
I do have run opam update.
I'm using OPAM 1.2.0.
Sadly verbose mode returns me nothing more than the previous listing.
Running opam remote returns me the following listing:
$ opam remote
10 [git] company ssh://git#host:port/opam-repository.git
0 [http] default https://opam.ocaml.org
BTW: what is the meaning of the numbers in the first column of this listing? Priority ?
I just had the same error and the issue was that there was a typo in one dependency of the <package> (see opam file). That could be a path to explore...
