mysql-server

Hi,

I've a problem with the dependencies of two packages, so I've tried to do:

apt-get -f install

dpkg: dependency problems prevent configuration of mysql-server-5.5:
 mysql-server-5.5 depends on mysql-server-core-5.5 (= 5.5.29-0ubuntu0.12.04.1); however:
  Version of mysql-server-core-5.5 on system is 5.5.29-0ubuntu0.12.04.2.
dpkg: error processing mysql-server-5.5 (--configure):

 mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

In this moment I can't install any package nor upgrade it with apt-get upgrade and I can't use apt-get autoremove because Ubuntu returns me this message:

The following packages have unmet dependencies:
 mysql-server-5.5 : Depends: mysql-server-core-5.5 (= 5.5.29-0ubuntu0.12.04.1) but 5.5.29-0ubuntu0.12.04.2 is installed
E: Unmet dependencies. Try using -f.

do you have any suggestion?
