This morning the system gave me a message that my Version (11.4) was no longer supported, and I took the 'upgrade' option (-> 11.10). While installing the various components I encountered a message to the effect that the there was an error and the system may have become unusable.

Among the messges: E:Sup-process /usr/bin/dpkg received a segmentation fault...returned an error code (1).

I was given an option to do several things, one of which seemed to mean that it would attempt to roll back to the previous version (the default), which I took. After the process ran it said the upgrade process had finished, but there were errors. I attempted to initialize a console so I could enter ubuntu-bug update-manager /var/log/dist-upgrade, per the instructions I received when I received the error message, but the console failed during initialization.

I restarted the machine, and the screen has stopped with the following contents: * Starting bluetooth * Stopping save kernel messages * Starting CUPS printing spooler/server * PulseAudio configured per-user sessions saned disabled: edit /etc/default/saned $starting up Cisco VPN daemon *Starting anac(h)ronistic cron *Stopping anac(h)ronistic cron

Each of these steps followed by [ OK ]

What are my options?

Any help appreciated!
