[PLUG] Upgrading Issues - Broken Dependency wanted to uninstall window manager

[Joseph Hume]

Recently I was updating my Debian Testing (Currently Wheezy) laptop.  
After updating the local packages with aptitude update to update the 
local lists I found that there where 404 updates available for my 
system.  Issuing the aptitude dist-upgrade command brought up a list of 
the packages that would be installed, a couple of broken dependencies, 
and a list of the packages that would be removed including my window 
manager.

The primary dependency breaker =>  mysql-common : Breaks: 
mysql-server-core-5.1 (< 5.5) but 5.1.62-1 is to be installed.  
mysql-common requires a minimum version of mysql-server-core of v5.5.

Looking at the software installed on my laptop I have
root at d9300:/home/joseph# dpkg -l | grep mysql-server
ii  mysql-server-core-5.1                
5.1.61-3                           MySQL database server binaries

Looking at the software available I have available
root at d9300:/home/joseph# apt-cache search mysql-server
auth2db - Powerful and eye-candy IDS logger, log viewer and alert generator
mysql-server-5.1 - MySQL database server binaries and system database setup
mysql-server-core-5.1 - MySQL database server binaries
mysql-server - MySQL database server (metapackage depending on the 
latest version)
mysql-server-5.5 - MySQL database server binaries and system database setup
mysql-server-core-5.5 - MySQL database server binaries
torrentflux - web based, feature-rich BitTorrent download manager

I issue the command to upgrade mysql-server-core and resolve the primary 
blocker
# aptitude install mysql-server-core-5.5
dpkg: mysql-server-core-5.1: dependency problems, but removing anyway as 
you requested:
  akonadi-backend-mysql depends on mysql-server-core; however:
   Package mysql-server-core is not installed.
   Package mysql-server-core-5.1 which provides mysql-server-core is to 
be removed.

I was able to download and install all pending updates and keep my 
window manager!

Hope this helps someone.
