The subject line says it all. I have a condition where apt-get refuses to
upgrade. How can I figure out exactly what apt-get does not like:
Here follows my example run. The reason I use a versioned install is just
because otherwise apt-get just refuses to consider the upgrade. This is a
problem I have gotten before and found it quite hard to figure out the
reason, and is never sure if I really got the right solution. There must be a
way to figure out exactly what goes wrong.
First:
shakti:~# dpkg --compare-versions '4:3.1.0++kl-1' '>' '4:3.1.0+rc6+kl-3'; echo
"$?"
0
Ok, version 4:3.1.0++kl-1 is the greater version.
Now:
shakti:~# apt-get install -t unstable libkdecore4
Reading Package Lists... Done
Building Dependency Tree... Done
Sorry, libkdecore4 is already the newest version.
Done
0 packages upgraded, 0 newly installed, 0 to remove and 58 not upgraded.
Ooops. already the newest version?
But what about the following, and the compare-version above:
shakti:~# apt-cache show libkdecore4 | grep Version
Version: 4:3.1.0++kl-1
Version: 4:3.1.0+rc6+kl-3
shakti:~#
Let's try this:
shakti:~# apt-get install -t unstable libkdecore4=4:3.1.0++kl-1
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:
Sorry, but the following packages have unmet dependencies:
libkdecore4: Depends: libdcop4 (>= 4:3.1.0++kl) but 4:3.1.0+rc6+kl-3 is to
be installed
Depends: libkdefx4 (>= 4:3.1.0++kl) but 4:3.1.0+rc6+kl-3 is to
be installed
Depends: kdeinit4 (= 4:3.1.0++kl-1) but 4:3.1.0+rc6+kl-3 is to
be installed
Depends: libkdecore-data but it is not going to be installed
E: Sorry, broken packages
Note here that all those missing packages are existing, and according to the
dpkg compare-version above, have higher version numbers. apt-get is doing the
wrong thing above. Why is it not updating those packages shown, libdcop4,
libkdefx4 and kdeinit4, when there are newer version available that will
satisfy the dependencies?
the full output of the run follows in the end
