Strange. I have this problem also in the Gutsy Beta as well. I have no clue what it could be upgrading to.

Add another occurrence. AMD64, clean install - trying to finish install by updating latest packages.
Very similar apt-log.

Confirmed on Gutsy (was originally installed during Tribe 1 times) AMD64

Could not calculate the upgrade

A unresolvable problem occurred while calculating the upgrade.

Please report this bug against the 'update-manager' package and include the following error message:
'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'

I was offered a partial upgrade this morning, ran it, computer was fine since then (through reboots even). Just got the update notification again, now this error.

[Kansei (clauretano)]

Running (as root)

aptitude update

then

aptitude safe-upgrade

seems to work around it. I was able to check for updates and it is now downloading and installing them.

[Kansei (clauretano)]

Whatever you guys do, don't run a dist-upgrade through aptitude.

It showed 4 unresolved dependencies. To 'fix' the first one, the 'ubuntu-desktop' metapackage has to be removed, as well as a couple others. Run dist-upgrade again, it wants to remove pidgin, udev, etc.. run it again, and it wants to remove over 500 packages on the system, including everything xorg and gnome-related in any way.

[Kansei (clauretano)]

This fixed it for me:
-Run synaptic
-"Refresh" to pull package lists
-"Mark all upgrades"
-search for any packages you know got removed by a dist-upgrade if you ran it. For me, I told it to reinstall pidgin, AccessGrid, and ubuntu-desktop (which installed two other trivial packages).
-"Apply"

[Nanley Chery (nanoman)]

I did not change any settings and the problems fixed itself. I updated today, and I wasn't notified for a dist upgrade, just the usual regular updates.

[McCown (steven-mccown)]

I had the same problem and just fixed it. A while ago, I had installed Ubuntu (GNOME) 7.07 and then used synaptic to also install kubunutu-desktop (KDE). This gave me the use of most of the KDE apps while running GNOME. Kind of neat.

During the upgrade, I discovered that my Gutsy Alternate CD for Ubuntu (GNOME) didn't have the upgrade packages for kubuntu-desktop (duh). Since I had told the installer not to download new updates, it was having a problem proceeding with a gutsy upgrade while a feisty kubunutu-desktop remained.

My solution was to let the alternate cd go online to download the required packages that weren't on my cd. This way, everything upgrades and the conflict goes away.

Another solution would likely have been to uninstall kubuntu-desktop using synaptic.

Hope this helps...

[McCown (steven-mccown)]

Sorry, that was Ubuntu 7.04 -- I don't want to introduce more confusion...

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

I have not seen this issue since this version.
