Tested on laptop HP Pavilion N5472 KDE 3.5.5 Followed the instructions on the dist-upgrade wiki page. The upgrade tool proceeds successfully until it gets to the 'cleaning up' step. Then it hangs with the error 'E:Sub-process /usr/bin/dpkg returned an error code (1)' that others have reported previously.
tail /var/log/dist-upgrade/main.log shows the following: 2007-03-24 22:14:35,469 DEBUG 'linux-image-2.6.17-11-generic' scheduled for remove but not in remove_candiates, skipping 2007-03-24 22:14:55,576 DEBUG 'linux-image-2.6.17-10-generic' scheduled for remove but not in remove_candiates, skipping 2007-03-24 22:15:09,682 DEBUG 'linux-restricted-modules-2.6.17-11-generic' scheduled for remove but not in remove_candiates, skipping 2007-03-24 22:15:24,288 DEBUG 'linux-restricted-modules-2.6.17-10-generic' scheduled for remove but not in remove_candiates, skipping 2007-03-24 22:15:33,792 DEBUG Finish checking for obsolete pkgs 2007-03-24 22:15:35,067 DEBUG The following packages are remove candidates: linux-headers-2.6.17-11-generic libdns21 libgpod0 libavahi-core4 libdirectfb-0.9-24 linux-headers-2.6.17-10 libicu34 linux-headers-2.6.17-10-generic linux-headers-2.6.17-11 libtunepimp3 2007-03-24 22:16:47,445 DEBUG fork pid is: 1648 2007-03-24 22:16:47,502 DEBUG fork pid is: 0 2007-03-24 22:21:27,972 ERROR cache.commit() in doPostUpgrade() failed: E:Sub-process /usr/bin/dpkg returned an error code (1) 2007-03-24 22:25:22,388 WARNING no activity on terminal for 240 seconds (Removed linux-headers-2.6.17-11) I have attached the rest of main.log for reference. apt.log also has this QGVector::insert: Index 4664 out of range Starting Starting 2 Package linux-restricted-modules-2.6.17-11-generic has broken dep on linux-image-2.6.17-11-generic Considering linux-image-2.6.17-11-generic 10001 as a solution to linux-restricted-modules-2.6.17-11-generic 0 Removing linux-restricted-modules-2.6.17-11-generic rather than change linux-image-2.6.17-11-generic Done Starting Starting 2 Package linux-restricted-modules-2.6.17-10-generic has broken dep on linux-image-2.6.17-10-generic Considering linux-image-2.6.17-10-generic 10001 as a solution to linux-restricted-modules-2.6.17-10-generic 0 Removing linux-restricted-modules-2.6.17-10-generic rather than change linux-image-2.6.17-10-generic Done X Error: BadWindow (invalid Window parameter) 3 Major opcode: 4 Minor opcode: 0 Resource id: 0x420a0b7 There are lots more X errors although I don't claim to understand this lot, I have attached apt-log.
