mediaarea mediainfolib DOWNGRADE

Affected: 26.01

Fixed in: no fixed release known

Safe to downgrade to: a release before 26.01

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 26.01 (Debian / Ubuntu)

apt-cache madison mediainfolib sudo apt install mediainfolib=<VERSION_BEFORE_26.01> sudo apt-mark hold mediainfolib

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

dnf --showduplicates list mediainfolib sudo dnf downgrade mediainfolib-<VERSION_BEFORE_26.01> sudo dnf versionlock add mediainfolib

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.
