@marian: can you confirm what version of systemd-timesyncd is installed and available from the archive at the point you try and install MAAS?

Correction - on one controller there is 3.6, I will check if upgrade helps

We had an issue with our MAAS nodes where the first one could not apt update. After I fixed it manually, issue from this bug report is gone.
