Comment 15 for bug 1903776

I also verified landscape-client 19.12-0ubuntu10.1 from impish-proposed.
I used the same landscape-server-quickstart from ppa:landscape/19.10 as previously, with the same database query to enable upgrading.

Again, upgrade tool downloaded and validated successfully on the proposed version, with the upgrade successful and the
logs confirming the success:
