oracle mysql server UPGRADE

Affected: >= 8.4.0 and <= 8.4.10 · 9.7.0 · 9.7.1

Fixed in: newer than 8.4.10

Safe to downgrade to: a release before 8.4.0

1. Check installed version

apt-cache policy mysql-server || rpm -q mysql-server || mysql-server --version

2. UPGRADE to newer than 8.4.10 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade mysql-server

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 8.4.0 (Debian / Ubuntu)

apt-cache madison mysql-server sudo apt install mysql-server=<VERSION_BEFORE_8.4.0> sudo apt-mark hold mysql-server

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list mysql-server sudo dnf downgrade mysql-server-<VERSION_BEFORE_8.4.0> sudo dnf versionlock add mysql-server

Downgrade risk
