I have a server running on Debian wheezy with MaraiDB and OwnCloud. Few days ago, I wanted to update the packages because of the OwnCloud updates but something went wrong.

Usually in this case I'd probably try to remove and again install the problematic packages, but on a server which is used by different people it doesn't seem like a valid solution anymore.

Here you can see my console output:

user@server:~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libmariadbclient18 : Depends: libmysqlclient18 (= 10.0.4+maria-1~wheezy) but 10.0.5+maria-1~wheezy is installed
 libmysqlclient18 : Depends: libmariadbclient18 (= 10.0.5+maria-1~wheezy) but 10.0.4+maria-1~wheezy is installed
 mariadb-client-10.0 : Depends: libmariadbclient18 (>= 10.0.5+maria-1~wheezy) but 10.0.4+maria-1~wheezy is installed

 mariadb-server-core-10.0 : Depends: libmariadbclient18 (>= 10.0.5+maria-1~wheezy) but 10.0.4+maria-1~wheezy is installed
E: Unmet dependencies. Try using -f.

I tried removing the 10.0.4 package version of libmariadbclient18 but I wasn't really successful in doing that.

So my last hope is here, do you have any ideas how exactly I could fix this issue?

Thx very much
