Fixed in: no fixed release known

Safe to downgrade to: a release before 2022

1. Check installed version

apt-cache policy idealms || rpm -q idealms || idealms --version

2. No fixed release: DOWNGRADE to a release before 2022 (Debian / Ubuntu)

apt-cache madison idealms sudo apt install idealms=<VERSION_BEFORE_2022> sudo apt-mark hold idealms

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list idealms sudo dnf downgrade idealms-<VERSION_BEFORE_2022> sudo dnf versionlock add idealms

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.
