I try to install nginx on an Ubuntu 20.04 AWS EC2 server by doing:
sudo apt update
sudo apt upgrade
sudo apt install nginx
However the last command fails:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
nginx : Depends: libssl1.0.0 (>= 1.0.2~beta3) but it is not installable
E: Unable to correct problems, you have held broken packages.
Any ideas on how to resolve this? Thanks in advance
Try the following:
echo "deb http://security.ubuntu.com/ubuntu bionic-security main" | sudo tee -a /etc/apt/sources.list.d/bionic.list
sudo apt update
apt-cache policy libssl1.0-dev
sudo apt-get install libssl1.0-dev

I've tried "apt-get install python-mysqldb" which results in:
root#ps1svr:~# apt-get install python-mysqldb
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package python-mysqldb is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'python-mysqldb' has no installation candidate
Note: "apt-get install python3-mysqldb" works, however I have a lot of code written for Python 2.x which no longer runs, and this is causing enough problems that I'm probably going to have to reinstall Ubuntu 18.04
Also you can just add the Ubuntu 18.04 repositoery to install the python-mysqldb package:
sudo add-apt-repository 'deb http://archive.ubuntu.com/ubuntu bionic main'
sudo apt update
sudo apt install -y python-mysqldb
This will download, build and install it for all users, using pip
sudo apt install libmysqlclient-dev python2.7-dev
wget https://bootstrap.pypa.io/get-pip.py
sudo python2.7 get-pip.py
sudo wget https://raw.githubusercontent.com/paulfitz/mysql-connector-c/master/include/my_config.h -O /usr/include/mysql/my_config.h
sudo pip2 install MySQL-python

Im following these steps to install gRPC on my freshly launched AWS EC2 Instance:
https://jitpaul.blog/2018/04/18/grpc-on-aws/
When I try to execute this line:
sudo yum install libgflags-dev libgtest-dev
I get this error:
I don't want to mess up anything, please help.
Try instead:
sudo yum install gflags-dev
sudo yum install gtest-dev
That should install libgflags-dev and libgtest-dev.
I am trying to install virtualbox5.2 on a RHEL 7 VM When I try to rebuild kernels modules I get the following error:
[root#myserver~]# /usr/lib/virtualbox/vboxdrv.sh setup
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is currently not set up to build kernel modules.
Please install the Linux kernel "header" files matching the current kernel
for adding new hardware support to the system.
The distribution packages containing the headers are probably:
kernel-devel kernel-devel-3.10.0-693.11.1.el7.x86_64
I tried install kernet-devel and got success message
Installed:
kernel-devel.x86_64 0:3.10.0-693.21.1.el7
Complete!
But still the setup fails.
Any idea what is missing here?
sudo yum install -y "kernel-devel-$(uname -r)"
Substitute dnf on Fedora. I didn't need to do a reboot, but ymmv.
Edit for 2020:
Centos/RHEL 8 now also use dnf instead of yum. I haven't had occasion to test this on those distros, so the same YMMV disclaimer still applies.
First run in terminal: uname -r then you will get name and information about current kernel (CURRENT_KERNEL).
Now you can install with command: yum install kernel-devel-CURRENT_KERNEL
Note: replace CURRENT_KERNEL with string you get from uname -r.
The same message happened when I tried to upgrade VirtualBox 5.2.12 Guest Additions on my Kali Linux (GNU/Linux Rolling version). I fixed it by following steps:
Do apt update/upgrade to keep your system up-to-date. Do not forget to reboot the system.
Run "apt-get install linux-headers-$(uname -r)".
Run VBoxLinuxAdditions.run from terminal, error message gone and Guest Additions will be installed successfully.
Reboot system, Guest Additions works fine.
I got here looking for the same answer for CentOS 6, and the above answers worked with slight modification (so, for anyone else that lands here too)...
yum install -y kernel-devel kernel-devel-$(uname -r)
So, "yum" instead of "apt-get"
Also, some Linux use "linux-headers" instead of "kernel-devel" but the principle seems to be the same.
The kernel your were using was kernel-devel-3.10.0-693.11.1.el7.x86_64 is slightly different with the one that you installed kernel-devel.x86_64 0:3.10.0-693.21.1.el7 . In my case, there are several different version installed on my OS, and "sudo yum install kernel-devel" always install the newest one for me. Then I work it out by setting my default kernel version as same as yum installed for me. You can check the kernel you have installed on your OS by following command:
sudo awk -F\' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2.cfg
Then just set the kernel version you choose to use as same as yum choose for you,by following command:(notice that the number at last is pick up from preceding command result),
sudo grub2-set-default 0
generate the grub2 config with 'gurb2-mkconfig' command, and then reboot the server.
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
sudo reboot
Milan Rakos is right. Your installed kernel-devel must have suffix string exactly the same as the uname -r output. Besides, the logs during the vboxdrv.sh setup also shows the wanted version of the kernel-devel.
So to your case, You will run the command:sudo yum install kernel-devel-3.10.0-693.11.1.el7.x86_64
to solve this problem I ran yum update -y. I think this is the fastest way to solve it. Another solution is to configure the repos with the installation DVD, so you can install the kernel-headers of your current version of CentOS.
My History:
yum install epel-release
yum install perl gcc dkms kernel-devel kernel-headers make bzip2
yum groupinstall "Development tools"
yum update -y
reboot
After that, I mount de VBoxGuestAdditions and I ran the process
yum install kernel-devel-3.10.0-693.11.1.el7.x86_64 fixed the issue.
A little late to the party but I just ran into this problem myself and here's what I did to resolve the issue.
yum update -y
yum install -y redhat-lsb-core net-tools kernel-headers kernel-devel epel-release
yum groupinstall -y "Development Tools"
reboot
Ensure your system has been fully updated when you ran yum update -y before continuing!
Cheers
I need to install php-imap on amazon ec2 linux 2 instance.
All the php stuff is inside amzn2extra-lamp-mariadb10.2-php7.2 but php-imap package is missing.
Any advice ?
Thanks
I installed it like this.
I downloaded the php source code of the currently installed version in my Amazon Linux 2
wget http://php.net/get/php-7.2.8.tar.bz2/from/a/mirror
Unpacked it and went into php-7.2.8/ext/imap/
Compiled extension:
phpize
./configure
I got some errors.
Some U8T_CANONICAL stuff so
sudo yum install libc-client-devel
Then libc-client.a not found so created a symlink for it:
cd /usr/lib
sudo ln -s /usr/lib64/libc-client.a
some other imap library error so:
sudo yum install uw-imap-static
I got some other errors so the working configure line was:
./configure --with-kerberos --with-imap-ssl
make
SUCCESS!
cd php-7.2.8/ext/imap/modules
sudo cp imap.so /usr/lib64/php/modules/
Created an ini file to load it:
sudo vi /etc/php.d/30-imap.ini
added to the file this content:
extension=imap
restarted php service (you might need to restart httpd depending on your php installation):
sudo systemctl restart php-fpm
PHPinfo now contains:
imap
IMAP c-Client Version 2007f
SSL Support enabled
Kerberos Support enabled
For those who are facing the U8T_CANONICAL error and can't being able to install the libc-client-devel on Amazon Linux 2 AMI need to do something extra to resolve the U8T_CANONICAL error.
The main problem is that libc-client-devel isn't available so we need to do it in another way.
I found this link while searching for my problem. The solution that is posted here is solid. The following link that i gave is for those who are not being able to install the libc-client-devel will be benifited from the link.
Or you could just copy paste the commands i'm giving below.
1 - sudo yum groupinstall "Development Tools"
2 - sudo amazon-linux-extras install epel
3 - yum install epel-release
4 - sudo yum install libc-client-devel uw-imap-static openssl-devel
5 - sudo ln -s /usr/lib64/libc-client.a /usr/lib
The rest can be followed from respondent.
Again thanks to the person who answered.
Same problem here.
I came from debian/ubuntu and i miss a lot of php packages on aws linux2.
I know it's still a candidate and not a final LTS release. Only worked for a month with this distro and saw a lot of changes and updates. Some php dependencies can be solved with pear or pecl, but I couldn't get nothing working on php-imap.
php-imap depends on libc-client (maybe that's a problem?)
Here is my solution.
Search for the libc-client rpm that correspond to your version and
install manually.
Search for the rpm that corresponds to your php installed version. In my case it was 7.2.5**-2** about 2 weeks ago. (today is
7.2.5**-3** ) and isntall manually
CODE
wget https://dl.iuscommunity.org/pub/ius/stable/CentOS/7/x86_64//php72u-imap-7.2.5-2.ius.centos7.x86_64.rpm -P /tmp
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libc-client-2007f-16.el7.x86_64.rpm -P /tmp
rpm -i /tmp/libc-client-2007f-16.el7.x86_64.rpm
rpm -i /tmp/php72u-imap-7.2.5-2.ius.centos7.x86_64.rpm
If it fails because Failed dependencies:
rpm -ivh /tmp/php72u-imap-7.2.5-2.ius.centos7.x86_64.rpm --nodeps
I dont like this solution, but can't find for now any other solution more stable and easy. It will be a pain with updates....
I have successfully installed php70 and mysql. But when i am trying to install phpmyadmin by
$ sudo yum-config-manager --enable epel
And Then
$ sudo yum install -y phpMyAdmin
It gives me
--> Finished Dependency Resolution
Error: php70-common conflicts with php-common-5.3.29-1.8.amzn1.x86_64
Error: php56-common conflicts with php-common-5.3.29-1.8.amzn1.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Also after google sometimes i found a solution that try this
sudo yum install php70-mbstring
And i have tried this also, Still facing same error.
Any suggestion...?
I guess that you are following the Amazon tutorial to install phpMyAdmin ?
I had the same problem today and resolved it by uninstall PHP 7.0 with the yum command (the same given by Amazon with 'remove' instead of 'install' :
sudo yum remove httpd24 php70 mysql56-server php70-mysqlnd
and installed PHP 5.6 instead :
sudo yum install httpd24 php56 mysql56-server php56-mysqlnd
I don't know if this is a good solution, but it worked and I could install phpMyAdmin without dependencies problem. I hope it will help :)
In case you want to keep php7, I found a solution with AWS Amazon experts.
Just use :
sudo yum install -y php70-mbstring
I was having the same issue today. I had some success downloading phpmyadmin from phpmyadmin.net, and following their instructions. I did run into a different problem during the setup of phpmyadmin....
So, I punted on resolving this with the Amazon AMI for now, and chose to install the Bitnami LAMP AMI to get me going quicker. It comes with phpmyadmin configured.
NOTE: Bitnami's AMI is running PHP Version 5.6.29, so I would say it's valid to follow the previous post's advice and downgrade, unless your web application specifically needs PHP 7.0.
