tdarr tdarr DOWNGRADE

Affected: 2.00.15

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.00.15

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.00.15 (Debian / Ubuntu)

apt-cache madison tdarr sudo apt install tdarr=<VERSION_BEFORE_2.00.15> sudo apt-mark hold tdarr

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

dnf --showduplicates list tdarr sudo dnf downgrade tdarr-<VERSION_BEFORE_2.00.15> sudo dnf versionlock add tdarr

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.
