I'm trying to install a ROS package (MAVROS) on my raspberry pi 3, but i can't find a way to do it. Other packages worked well, but this one starts aggravating me...
Specs:
ROS Kinetic
Rasbian
Can anyone help my with this?
Thanks!
First, add the ROS repository address to the source list.
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu trusty main" > /etc/apt/sources.list.d/ros-latest.list'
and add public key to the ROS package.
wget https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -O - | sudo apt-key add -
and you need a update.
then, install ROS Kinetic.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ros-kinetic-desktop-full

How can I install redis-cli only on CentOS, I know how to do it on ubuntu "sudo apt-get install redis-tools" but looking for similar package for CentOS.
If you are using amzn linux 2:
sudo amazon-linux-extras install epel -y
sudo yum update
sudo yum install redis
I am familiar with this approach:
wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make
cp src/redis-cli /usr/local/bin/
chmod 755 /usr/local/bin/redis-cli
as you can see above, here you have to compile the source code using make. You hence need to make sure that you have c compiler on your OS. If you do not, then this can help you:
sudo yum install gcc
Also be aware, that this approach will also create another executables in src/ folder. I recommend you to check this out here.
hope it helped, have a nice day!
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
Answer found from MySQLdb install error - _mysql.c:44:23: error: my_config.h: No such file or directory
I am trying to install AWS SAM (Serverless Application Model) Local on Ubuntu 16.04.
I tried to install SAM Local using NPM with the following command.
npm install -g aws-sam-local
I got the following error.
Please help me to sort it out?
Installation on Ubuntu 16.04/18.04
sudo apt-get install python3-pip -y
sudo -H python3 -m pip install aws-sam-cli
First try
npm config set unsafe-perm=true
I also installed node v8.11.1
The standard shebang for node is #!/usr/bin/env node. There is a package conflict with the name node, so it's named nodejs.
You can solve the issue with a symlink using alternatives.
sudo update-alternatives --install /usr/bin/node node /usr/bin/nodejs 10
first try
npm install -g go-npm
then
npm install -g aws-sam-local
If issue with current user permissions, please use sudo with below commands
First try,
npm config set unsafe-perm=true
Then,
npm install -g go-npm
finally,
npm install -g aws-sam-local
It will also work for mac.
I want to create a small mp3 player as a toy project so started with Qt for the GUI. When I try to play an mp3 file i get this error.

Error: "Your GStreamer installation is missing a plug-in."
I installed gstreamer and it's plugins after googling around
sudo apt-get install gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav
But I still get the error. How do I fix it?
I had the same problem.
After using below code it fixed.
sudo add-apt-repository ppa:mc3man/gstffmpeg-keep
sudo apt-get update
sudo apt-get install gstreamer0.10-ffmpeg
sudo apt-get install gstreamer0.10-plugins-ugly
Qt Creator 3.4.2 Ubuntu 14.04
I tried digging a little into this and according to this thread in the Qt forums the issue seems to be that the QtMultimedia module is still using GStreamer 0.10 as a backend - and from that it needs the gstreamer-0.10-ffmpeg plugin which is not available in some distros anymore due to the move to libav.
If you're using a flavour of Ubuntu you can try installing gstreamer-0.10-ffmpeg from Doug McMahon's ppa:
sudo add-apt-repository ppa:mc3man/gstffmpeg-keep
sudo apt-get update
sudo apt-get install gstreamer0.10-ffmpeg
On Debian8, QT5.7, I'm executing this:
sudo apt-get install gstreamer1.0*
sudo apt-get install gstreamer0.10*
this is not the best way, but it works.
Regards.
On Ubuntu20.04, I solved this problem by:
sudo apt-get install gstreamer1.0-libav
