Just happened to me as well (stuck at 75% complete). However I am able to ssh into the machine. This happened after I put an previous karmic xorg.conf back into /etc/X11/ to test an nvidia-96 problem (#523108 & #539196) and rebooted.

Nothing obvious in dmseg, xorg.0.log, nothing new in /var/log/fsck. Tail of .xsession-errors shows: ** (gnome-panel:1870): WARNING **: Failed to send buffer ** (gnome-panel:1870): WARNING **: Failed to send buffer The application 'gnome-panel' lost its connection to the display :0.0; most likely the X server was shut down or you killed/destroyed the application. so I'm thinking it may be related to the karmic xorg.conf file that I used. I'll try rebooting to see if any change (leaving the xorg.conf file in place). -- Lucid boot failed to complete after fsck https://bugs.launchpad.net/bugs/554079 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
