With MySQL 8.0.20 currently installed on Ubuntu, I am unable to use Percona XtraBackup 2.3.7 due to breaking changes introduced in MySQL 8.0.20.
How can we downgrade MySQL 8.0.20 to 8.0.19 on Ubuntu, which I believe is the latest MySQL version currently supported by XtraBackup? dpkg-reconfigure mysql-apt-config
does not allow us to select a minor version.
Must the current data be backup using mysqldump before the downgrade, and restored using the dump after the downgrade?

Xtrabackup 8.0.12 should work with MySQL 8.0.20
Percona xtrabackup 8.0.12 release
