Guys, I have recently upgraded from 11.10 to 12.04 and I have an error message when updating:
sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages have been kept back:
trac-wikiprint
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
When I try to re-install trac-wikiprint, I get:-
sudo apt-get install trac-wikiprint

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.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
trac-wikiprint : Depends: python-pil but it is not installable
E: Unable to correct problems, you have held broken packages.
That's easy, just install pythin-pil & it's all good:
sudo apt-get install python-pil
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package python-pil is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'python-pil' has no installation candidate
:confused:
So, where to next?
sudo apt-get upgrade
