Breezy -> Dapper upgrade tool fails

[Daniel Wiebelt]

I tried to upgrade from Breezy with

gksudo "update-manager -d"

as discribed on ubuntu.com/testing/dapperbeta. the upgrade tool starts, loads something and aborts with "A fatal error occured". This happens at step 3 (translated from german: "loading updates and installing"; under the Progress bar "Asking for confirmation"). the error is reproducible.

This is the error message:

The error message ask for reporting this Bug and adding ~/distupgrade.log and ~/dist-upgrade-apt.log which I rather found in /var/log. (I shortened the package listing).

Installing the ubuntu-base package removes this problem for me.

In order to do this I had to uncomment the breezy sources from /etc/apt/sources.list, since update-manager had commented them out.

However the process then failed while 'Downloading and installing the upgrades' with the message :

'Could not calculate the upgrade

A unresolvable problem occured while calculating the upgrade. Please report this as a bug. '

I am not sure if this is part of the same bug or another one.

Could you please try this again (in 3-4h)? I uploaded a new dist-upgrader that should fix the crash that was reported here.

About the "xchat" problem in the comment from Richard Wolf, this seems to be bug 41023.

Cheers,
 Michael

I experienced the exact same bug when I tried to update today, 11 May.

Thanks for this additional information. Is this all you had in your /var/log/dist-upgrade.log? No information about the sources.list being rewriten?

Thanks,
 Michael
