This update totally failed for me on Debian 10 and Ubuntu 20.04 servers.

I was upgrading from “percona-server-server-5.7:amd64 (5.7.38-41-1.focal)” to “5.7.39-42-1.focal” and I got errors, and now I’m unable to start Percona and I can’t downgrade it.

Any idea of how I could fix it please ?

**Edit :** Fixed in another topic, one variable was depreciated before and removed in this new version.
