vuplayer vuplayer DOWNGRADE

Affected: 2.49

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.49

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.49 (Debian / Ubuntu)

apt-cache madison vuplayer sudo apt install vuplayer=<VERSION_BEFORE_2.49> sudo apt-mark hold vuplayer

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

dnf --showduplicates list vuplayer sudo dnf downgrade vuplayer-<VERSION_BEFORE_2.49> sudo dnf versionlock add vuplayer

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.
