Public bug reported: I noticed today that I hadn't received any update notifications for a while, and after following the trail found in the output of /usr/lib /update-notifier/apt-check:
E: Unknown Error: '<class 'KeyError'>' ("The cache has no package named 'skype-bin'") Removing the exception hook from that file we find the actual error: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/apt/cache.py", line 198, in __getitem__ return self._weakref[key] File "/usr/lib/python3.4/weakref.py", line 125, in __getitem__ o = self.data[key]() KeyError: 'skype-bin' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "./apt-check", line 201, in <module> run(options) File "./apt-check", line 136, in run ignored = ul._is_ignored_phased_update(aptcache[pkg.name]) File "/usr/lib/python3/dist-packages/apt/cache.py", line 205, in __getitem__ raise KeyError('The cache has no package named %r' % key) KeyError: "The cache has no package named 'skype-bin'" This occurs when checking for phased updates, it tries to index the apt.Cache with the package name from the apt_pkg.Cache. But since the arch is amd64 and not i386, the package in the apt.Cache is instead skype-bin:i386. If we replace: ignored = ul._is_ignored_phased_update(aptcache[pkg.name]) with: ignored = ul._is_ignored_phased_update(aptcache[pkg.get_fullname(False)]) Everything seems to work fine.
