When installing on a fresh 20.04.1-Ubuntu instance I see the following message:

The packages are new as of this release I believe, so a little hiccup is expected I suppose. Can we see the full content of /var/lib/dpkg/info/tempo.postinst please?

yes no problem !

And the output of systemctl --version please.

@julienduchesne heads up :point_up:

systemctl --version | head -1 | awk '{print $2}' maybe, though I'm not sure if awk is common enough.
