Package: unattended-upgrades
Version: 2.11+nmu1
Severity: important
X-Debbugs-Cc: farb...@vodafonemail.de
Dear Maintainer,
* What led up to the situation?
unattended upgrade doing its job, configured to send email to local root as
Unattended-Upgrade::Mail "root";
* What exactly did you do (or not do) that was effective (or
ineffective)?
Letting unattended upgrade do its automatic background job.
* What was the outcome of this action?
The upgrade itself seems to have completed OK, but the final mail was not
sent due to the following Python error reported in
/var/log/unattended-upgrades/unattended-upgrades.log:

Get a mail with the upgrade results.
* Background information
This is most likely not a bug in u-u itself, but rather some dependency
issue. It should be related to a missing fix for Python bug
https://github.com/python/cpython/issues/121650.
