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 3.3.1 (Debian / Ubuntu)

apt-cache madison invision-power-board sudo apt install invision-power-board=<VERSION_BEFORE_3.3.1> sudo apt-mark hold invision-power-board

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.
