package mariadb-client-5.5 5.5.38-1 failed to install/upgrade: trying to overwrite '/usr/share/man/man1/innochecksum.1.gz', which is also in package mariadb-server-5.5 5.5.38-1

This error message is due to a file that has been re-located from the server package to the client package.

To recover from this, run 'sudo dpkg -r mariadb-server-5.5', then run the 'sudo apt-get upgrade' (or maybe 'sudo apt-get install -f') and then finally 'sudo apt-get install mariadb-server'. The removes will not remove any data or configuration, so after the last command your MariaDB server should be fully ready to continue as it was before.

Otto, that's brilliant, thank you!

The only thing I had to do differently was run 'sudo apt-get remove mariadb-server-5.5' as dpkg complained about dependencies.

Thank you!
