This only appears to occur on unattended upgrades. Additional logs are attached, and I'll attach some more shortly.

It's not really a bug with policykit-1, its just that the upgrader trips over this specific package.

For future reference one annoying thing about the non-interactive version of the upgrader is that it has its own exception handler e.g.:

class DistUpgradeViewNonInteractive(DistUpgradeView):
    " non-interactive version of the upgrade view "
    def __init__(self, datadir=None, logdir=None):
        DistUpgradeView.__init__(self)
        self.config = DistUpgradeConfig(".")
        self._acquireProgress = NonInteractiveAcquireProgress()
        self._installProgress = NonInteractiveInstallProgress(logdir)
        self._opProgress = apt.progress.base.OpProgress()
        sys.__excepthook__ = self.excepthook

Disabling sys.__excepthook__ allowed the real error, UnicodeDecodeError, to surface.

Using errors='ignore' allows the upgrade to complete and doesn't seem too horrible given that's its non-interactive anyway.

sys.stdout.write("%s" % s.decode(locale.getpreferredencoding(), errors='ignore'))

We can see the errors in the terminal output:

Preparing to unpack .../inputattach_1%3a1.5.1-2_amd64.deb ...
Unpacking inputattach (1:1.5.1-2) over (1:1.4.9-1) ...

Notice the ':' vs '%3a'. The same errors also appear in the log - /var/log/dist-upgrade/main.log.

Looking a /var/log/dist-upgrade/main.log though maybe its the arrow:

This bug was fixed in the package ubuntu-release-upgrader - 1:16.10.5

---------------
ubuntu-release-upgrader (1:16.10.5) yakkety; urgency=medium

  * DistUpgradeViewNonInteractive.py: Instead of tripping over errors when
    writing progress to stdout just ignore them so that the upgrade can
    continue. (LP: #1614576)

Hello Max, or anyone else affected,

Accepted ubuntu-release-upgrader into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ubuntu-release-upgrader/1:16.04.18 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
