Affected: <= 25.6.5 · >= 26.0 and <= 26.2.1

Fixed in: newer than 26.2.1

Safe to downgrade to: a release before 26.0

1. Check installed version

apt-cache policy after-effects || rpm -q after-effects || after-effects --version

2. UPGRADE to newer than 26.2.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade after-effects

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 after-effects sudo apt install after-effects=<VERSION_BEFORE_26.0> sudo apt-mark hold after-effects

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

dnf --showduplicates list after-effects sudo dnf downgrade after-effects-<VERSION_BEFORE_26.0> sudo dnf versionlock add after-effects

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.
