Safe to downgrade to: a release before 10.6.1
1. Check installed version
apt-cache policy mariadb || rpm -q mariadb || mariadb --version
2. UPGRADE to 10.6.28 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade mariadb
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade mariadb
Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 10.6.1 (Debian / Ubuntu)
apt-cache madison mariadb sudo apt install mariadb=<VERSION_BEFORE_10.6.1> sudo apt-mark hold mariadb
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list mariadb sudo dnf downgrade mariadb-<VERSION_BEFORE_10.6.1> sudo dnf versionlock add mariadb
Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
