12.04 fails to upgrade to 14.04.1

[Marijn Ros]

On my machine running 12.04 (original installation 10.10 prerelease), I cannot upgrade to 14.04.1. There is an error calculating dependencies.

As fas as I can see, I only have precise repositories. But in 4 years, I might have had some packages installed from another repository. But none that I can find in the pacakge manager are installed at this moment.

I tried removing all 'dummy'and 'transitional'packages (which succeeded for all but one package, that is a dependency of flightgear), but that didn't help.

In the apt.log file, I notice that flightgear and related packages are mentioned a lot.

I will see wat happens if I remove those before upgrading.

[Marijn Ros (marijn-mad)]

Removing flightgear (I removed all packages that synaptic showed when searching for flightgear and fgfs) indeed solved the issue.

So for me, this issue is no longer an issue.
