Hello again, thanks for the answer.
The result of e2fsck and memtest said the same: The machine had no problems passing both tests. The file system is clean and memtest was running for almost 3 hours and at pass 5 as I aborted it. Or how long should that take with the default options for memtest started from the unmodified grub entry? (My Machine has 1GB RAM and a 2,5 GHz Pentium IV.) But as you wrote the status of dpkg got possibly corrupted, I remembered some other strange behaviour. I tried to do the update 2nd time already, as the problem above happend. The first time I tried it my /etc/apt/sources.list got written with - for me - senseless content. So I couldn't used it at all. So I instructed Synaptic to recreate a new sources.list by adding the official entrys of Ubuntu 7.10. Then I started the 2nd try to update my system and resulted in the current situation. One last thing that I want to mention: I had no stability problems with other debian-based distributions (but those were based on sarge and later on etch) in the past, but starting with Ubuntu 7.10 my system sometimes completly got frozen and nothing worked then, not even killing the X-window-system by pressing the CTRL+ALT+Backspace... I haven't figured out, why and when that happend. Because it was completly irregular. My guess was that this maybe was caused by the ATI drivers as I installed the ones from their website. I attached the file you ask for, this time I managed it to compress it with as .tar.gz. ** Attachment added: "/var/lib/dpkg/status" http://launchpadlibrarian.net/14262760/dpkg-status.tar.gz -- Update failed while installing packages (7.10 to 8.04) - System now hangs during booting up https://bugs.launchpad.net/bugs/227031 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
