stlport project stlport DOWNGRADE

Affected: 5.0.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.0.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 5.0.2 (Debian / Ubuntu)

apt-cache madison stlport sudo apt install stlport=<VERSION_BEFORE_5.0.2> sudo apt-mark hold stlport

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

dnf --showduplicates list stlport sudo dnf downgrade stlport-<VERSION_BEFORE_5.0.2> sudo dnf versionlock add stlport

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.
