Dear Maintainer,

*** Reporter, please consider answering these questions, where
appropriate ***

the installed version is V-6.6.2-2. The problem arose while upgrading to
V-6.6.2-3

   * What led up to the situation?
apt dist-upgrade

   * What was the outcome of this action?
apt-listchanges: Reading changelogs...
(Reading database ... 653587 files and directories currently installed.)
Preparing to unpack .../fetchmail_6.6.2-3_amd64.deb ...

needrestart is being skipped since dpkg has failed
Error: Sub-process /usr/bin/dpkg returned an error code (1)

   * What outcome did you expect instead?
fetchmail upgrade to 6.6.2-3


fetchmail is running here in an user context (since about two decades).
Why would I ever need a fetchmail.service Unit? In the past upgrades
went smooth, though.

Thanks and bye
