I believe it's a known bug and it has been already reported at least one time: bug #75504.

Oops, in fact bug #75504 is probably not related at all to this one.

But I read about this issue on #ubuntu-devel and it isn't a bug in update-manager, it also happens on the buildds.

i think there are two sides to this issue.

one is the same issue that is in 75504 which is that libstdc++ can't be upgraded due to a dependency problem and the old libstdc++ is blocking other upgrades.

the other is that dist-upgrade is presenting a soloution to an upgrade request that involves removal of essential packages rather than a soloution that involves some stuff not being upgraded.

@John: this one is not related to the graphical dist-upgrade tool. apt seems to need a rebuild.

Setting it as a duplicate for now, but I agree that the problem resolver is doing stupid things here.

sebastian at the time he filed the bug i only new he ran update-manager and yes it looks like its dist-upgrader causing the issue and only way i would have known for sure was to see the logs. but i founnd out the logs are not anywhere on his system because he is in a chroot, but i thought they would still be there. this morning i was gonna have Michael give me his opinion on it since apt in any form is not causing this issue other than in a chroot . he has same version of apt as i do (this was fixed in the newest apt)afaik. so my thought was update-manager had something to do with it. i talked with the reporter for a while in #ubuntu+1 to get as much info as i can but didnt get too much.

Peter please try update-manager to finish the issues now. the libstdc++6 has been released for update this should be good to upgrade now. but im sure the issue still is around just not for this set of upgrades. (nothing is held back atm)

I did not run update manager and never did i say that i did, its a minimal chroot and I don't even think i have update manager installed.

I used apt-get dist-upgrade yesterday without problems, but that is almost certainly the result of the archive being fixed rather than apt being made more sensible.

Peter sorry i was just reading logs and it was someone else in another channel that had the update-manager issue.

i dont think its only the update-manager

i just did an apt-get dist-upgrade and it removed ubuntu-desktop along with most of gnome...

im writing this from a partition with edgy...

afaik all the packages failed because they required some patch0.26 or other...

regardless - apt should solve it by holding and not by uninstalling ubuntu-desktop or other essential pieces.

thanks
