3. If no update is available yet, DOWNGRADE to a release before 8.10 (Debian / Ubuntu)

apt-cache madison maximo-application-suite sudo apt install maximo-application-suite=<VERSION_BEFORE_8.10> sudo apt-mark hold maximo-application-suite

dnf --showduplicates list maximo-application-suite sudo dnf downgrade maximo-application-suite-<VERSION_BEFORE_8.10> sudo dnf versionlock add maximo-application-suite

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.
