This appears to be happening because 20.04 LTS has "fs.protected_regular
= 1" by default and "galera_recovery" in MariaDB 10.3 doesn't support
this. It has been fixed upstream in MariaDB 10.5
(https://github.com/MariaDB/server/pull/1417/files) but hasn't been
backported to 10.3.22.
Applying the fix to /usr/bin/galera_recovery fixes the issue.
