minidvblinux minidvblinux DOWNGRADE

Affected: 5.4

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.4

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 5.4 (Debian / Ubuntu)

apt-cache madison minidvblinux sudo apt install minidvblinux=<VERSION_BEFORE_5.4> sudo apt-mark hold minidvblinux

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

dnf --showduplicates list minidvblinux sudo dnf downgrade minidvblinux-<VERSION_BEFORE_5.4> sudo dnf versionlock add minidvblinux

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.
