Public bug reported:
This is what I get when running unattended-upgrades --debug:
Initial blacklisted packages:
Starting unattended upgrades script
...
Traceback (most recent call last):
File "/usr/bin/unattended-upgrades", line 491, in <module>
main()
File "/usr/bin/unattended-upgrades", line 292, in main
logging.debug("Checking: %s (%s)" % (pkg.name, map(str,
pkg.candidate.origins)))
AttributeError: 'NoneType' object has no attribute 'origins'
The problem is that the unattended-upgrades script doesn't check the
value of pkg.candidate before calling the origins attribute on it. As
can be seen in the apt.package.Package class, the candidate attribute
might be None:
def candidate(self):
"""Return the candidate version of the package.
This property is writeable to allow you to set the candidate version
of the package. Just assign a Version() object, and it will be set as
the candidate version.
"""
cand = self._pcache._depcache.get_candidate_ver(self._pkg)
if cand is not None:
return Version(self, cand)
Therefore, the unattended-upgrades script should expect this eventually.
This can easily be done by using getattr and returning an empty list
there are no candidates.
