[Bug 1361768] [NEW] apt-check fails with "The cache has no package named 'skype-bin'"

[Jason Conti]

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.
