Can anyone tell me if it is safe to do an apt-get purge mysql-server-5.5 in Debian after removing mysql-server-5.5 and installing mysql-server via the deb-Package officially provided by MySQL? Do I risk it removing the configs being used by mysql-server? Current state is:
ii mysql-community-server 5.6.25-1debian7
ii mysql-server 5.6.25-1debian7
rc mysql-server-5.5 5.5.39-1
A purge action on an already removed package by definition will try to remove the configuration files provided by that package.
You have installed a package from two different providers that most probably define the same conffiles. Find out which are these by issuing:
# dpkg-query --showformat='${Conffiles}\n' --show mysql-server
for installed packages, and/or by inspecting the contents of
$ cat /var/lib/dpkg/info/<package>.conffiles
for removed packages, provided you haven't cleaned the cache.
You could also try:
# dpkg --dry-run --purge mysql-server
To see what would happen.
If you really can't live with that rc status on the mysql-server-5.5 package, backup your configuration files, purge the package and restore the configuration files.
