widevine trusted application UPGRADE

Affected: >= 5.0.0 and <= 5.1.1

Fixed in: newer than 5.1.1

Safe to downgrade to: a release before 5.0.0

1. Check installed version

apt-cache policy trusted-application || rpm -q trusted-application || trusted-application --version

2. UPGRADE to newer than 5.1.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade trusted-application

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade trusted-application

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 5.0.0 (Debian / Ubuntu)

apt-cache madison trusted-application sudo apt install trusted-application=<VERSION_BEFORE_5.0.0> sudo apt-mark hold trusted-application

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list trusted-application sudo dnf downgrade trusted-application-<VERSION_BEFORE_5.0.0> sudo dnf versionlock add trusted-application

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.
