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 2024.2 (Debian / Ubuntu)

apt-cache madison tableau-server sudo apt install tableau-server=<VERSION_BEFORE_2024.2> sudo apt-mark hold tableau-server

dnf --showduplicates list tableau-server sudo dnf downgrade tableau-server-<VERSION_BEFORE_2024.2> sudo dnf versionlock add tableau-server

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.
