resolved reports Failed to send hostname reply: Invalid argument

[Clay Jackson]

According to https://github.com/systemd/systemd/issues/11626 this is fixed in version 248 of systemd.

Please make that version available to LTS 20.04.3

Thanks!

Why is this marked invalid?

[Daniel Manrique (roadmr)]

I marked it invalid for Ubuntu One SSO because it is NOT an Ubuntu One SSO issue. The systemd task is still filed/active, for that project's bug triagers to look at.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Nick Rosbrook (enr0n)]

The fix referenced upstream is included in Jammy and newer. At the moment I do not see a need to SRU this to Focal.
