So, while I was installing GitLab following the official tutorial I got an error on the Gems installation.
Gem files will remain installed in /home/git/gitlab/vendor/bundle/ruby/2.0.0/gems/mysql2-0.3.11 for inspection.
Results logged to /home/git/gitlab/vendor/bundle/ruby/2.0.0/gems/mysql2-0.3.11/ext/mysql2/gem_make.out
An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.
Looking online they say this problem comes often when some lib is missing.. and one comment confirm what I was scared of...
problem solve, type this command
sudo apt-get install libmysqlclient-dev
sudo apt-get install mysql
then run gem install mysql2
The problem is that I tried to install it but..
sudo apt-get install libmysqlclient-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libmysqlclient-dev 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
However the following packages replace it:
mysql-server-5.5
E: Package 'libmysqlclient-dev' has no installation candidate
and mysql-server-5.5 is already installed... How can I solve it?
