Comment 4 for bug 174088

I'm unable to install the gnome-panel-dbgsym package:

shakti:~$ sudo apt-get install gnome-panel-dbgsym
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
  gnome-panel-dbgsym: Depends: gnome-panel (= 1:2.20.0.1-0ubuntu6) but 1:2.20.1-0ubuntu1 is to be installed
E: Broken packages

Version of gnome-panel is 1:2.20.0.1-0ubuntu6

Can you fix the dbgsym package and re-open, I'll get the stack trace? There is definitely a problem...
