I can add some more details now: The first installation failed, giving first a non-fatal error about cupsys upgrade, then crashing in the process of writing the kernel image!!! Clearly, this left me with a non-working 2.6.22 (generic) kernel. I had to restore the partition from the image I made (PartitionImage + Knoppix saved my life, I strongly advice this combination!!!).
Then I tried again and it worked just fine. Differences between the first and the second time were: 1) The second time I did activate cupsys before upgrading, since I read in another bug report that having it turned down was a cause of failure 2) Maybe more important, I avoided uninstalling the nvidia drivers. Those were installed through the "envy" script. The first time I removed them as adviced on the envy website, and I did also purge compiz (which I had from the git repository). The second time I left everything as it was, and all I had to do at the end was downgrading some compiz packages which had not been overwritten by the upgrade (ccsm and a couple others). I hope this helps. -- package update-manager 1:0.81 failed to install/upgrade: ErrorMessage: SystemError in cache.commit(): E:Sub-process /tmp/tmpjP6Bsx/backports/usr/bin/dpkg returned an error code (1), E:Sub-process /tmp/tmpjP6Bsx/backports/usr/bin/dpkg returned an error code (1), E:Sub-process /tmp/tmpjP6Bsx/backports/usr/bin/dpkg returned an error code (1), E:Sub-process /tmp/tmpjP6Bsx/backports/usr/bin/dpkg returned an error code (1) https://bugs.launchpad.net/bugs/154697 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
