Package: unattended-upgrades
Version: 1.11.2
Severity: important
I've just upgraded to buster and /usr/bin/unattended-upgrade now fails with an
error:
Exception: 'NoneType' object has no attribute 'dependencies'
the problem is in transitive_dependencies():
for dep in pkg.candidate.dependencies:
pkg.candidate is None when the package is systemd (uninstalled).
I have /etc/apt/preferences.d/systemd as follow:
Package: systemd
Pin: release *
Pin-Priority: -1
version in stretch of the package was working fine
I've added:
if pkg.candidate is None:
return acc
before the for-loop
Regards
