adobe media encoder UPGRADE

Affected: <= 25.6.5 · >= 26.0 and <= 26.2.2

Fixed in: newer than 26.2.2

Safe to downgrade to: a release before 26.0

1. Check installed version

apt-cache policy media-encoder || rpm -q media-encoder || media-encoder --version

2. UPGRADE to newer than 26.2.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade media-encoder

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade media-encoder

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 26.0 (Debian / Ubuntu)

apt-cache madison media-encoder sudo apt install media-encoder=<VERSION_BEFORE_26.0> sudo apt-mark hold media-encoder

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

dnf --showduplicates list media-encoder sudo dnf downgrade media-encoder-<VERSION_BEFORE_26.0> sudo dnf versionlock add media-encoder

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.
