Hi Bruna, thanks for reporting this issue.
Just to confirm, are you using a custom python installation in the system ?

[Launchpad Janitor (janitor)]

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

This appears to be a duplicate of bug 1930121.

For now, the likely quick fix is to set PYTHONPATH=/usr/lib/python3/dist-packages

We will release a proper fix in ubuntu-advantage-tools in a coming release.
