Comment 32 for bug 990740

Problem also exists with Kubuntu. The upgrade was started with "do-release-upgrade"

"apport-cli -p update-manager -u 990740"
results in:
"Could not import module, is a package upgrade in progress? Error: No module named launchpadlib.errors"

"apt-get install -o APT::Immediate-Configure=false --reinstall python-minimal"

didn't help either:

Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  libc-dev-bin: Depends: libc6 (< 2.12) but 2.15-0ubuntu10 is to be installed
                Recommends: manpages-dev but it is not going to be installed
  libc6-dev: Depends: libc6 (= 2.11.1-0ubuntu7.10) but 2.15-0ubuntu10 is to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
