Public bug reported:
There's a red icon in my upper right task bar region that looks like an
international stop sign. When I click on it, it says to file a bug
report against the update manager with this line following:
'E:Malformed line 51 in source list /etc/apt/sources.list (dist parse)'
**
Thanks for you help. I renamed the sources.list to sources.old and did
an apt-get install update manager. This appears to have fixed the
issue, but I have attached the .old file to assist in troubleshooting
why it happened in the first place.
** Attachment added: sources.old
