[Bug 1112336] [NEW] [hardy->lucid] unresolvable problem occurred while calculating the upgrade

[Fionn]

Public bug reported:

Since hardy is nearing the end of its support cycle I initiated an upgrade to lucid. Unfortunately it failed miserably.
What I tried so far:

* disabling (the single one) ppa we had (git) and uninstall their git packages
* looking for broken packages (none found)
* making sure everything is the latest version
* starting do-release-upgrade in server and desktop mode (wont help)

Now I am out of ideas. Uninstalling update-manager-core looks like being
a really bad move for an update so I didnt try that one.

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade: 
The package 'update-manager-core' is marked for removal but it is in 
the removal blacklist. 

This can be caused by: 
* Upgrading to a pre-release version of Ubuntu 
* Running the current pre-release version of Ubuntu 
* Unofficial software packages not provided by Ubuntu 

If none of this applies, then please report this bug against the 
'update-manager' package and include the files in 
/var/log/dist-upgrade/ in the bug report.
