Public bug reported: In spite of apparent fixes for [bug #1342424] I find that the update- manager is still crashing and failing to perform the HWE upgrade to move my 12.04.4 LTS installation.
If I run the update-manager from the command line I get the same behaviour as the normal alert when updates are availabe, but also additional information. It proceds correctly until it has asked for the sudoer password, then it prints the error messages and triggers a crash report. $ /usr/bin/update-manager Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 473, in _inline_callbacks result = gen.throw(result.type, result.value, result.traceback) File "/usr/lib/python2.7/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 54, in commit yield self._run_in_dialog(trans, self.INSTALL) File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 473, in _inline_callbacks result = gen.throw(result.type, result.value, result.traceback) File "/usr/lib/python2.7/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 75, in _run_in_dialog yield dia.run() aptdaemon.errors.TransactionFailed: Transaction failed: None The following packages have unmet dependencies: libgl1-mesa-glx-lts-trusty: Depends: libglapi-mesa-lts-trusty (= 10.1.3-0ubuntu0.1~precise1) but 10.1.3-0ubuntu0.1~precise1 is to be installed Depends: libx11-6 (>= 2:1.4.99.1) but 2:1.4.99.1-0ubuntu2.2 is to be installed Depends: libxdamage1 (>= 1:1.1) but 1:1.1.3-2build1 is to be installed xserver-xorg-lts-trusty: Depends: xserver-xorg-core-lts-trusty (>= 2:1.11) but 2:1.15.1-0ubuntu2~precise1 is to be installed What I expect is the system to (A) correctly resolve and install the dependancies to get the HWE update, and (B) if it can't do that to not crash out when reporting the cause.
