tranquil wapt UPGRADE

Affected: < 1.8.2.7373 · >= 2.0.0.0 and < 2.0.0.9450

Fixed in: 1.8.2.7373, 2.0.0.9450

Safe to downgrade to: a release before 2.0.0.0

1. Check installed version

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

2. UPGRADE to 1.8.2.7373 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade wapt

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade wapt

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 2.0.0.0 (Debian / Ubuntu)

apt-cache madison wapt sudo apt install wapt=<VERSION_BEFORE_2.0.0.0> sudo apt-mark hold wapt

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

dnf --showduplicates list wapt sudo dnf downgrade wapt-<VERSION_BEFORE_2.0.0.0> sudo dnf versionlock add wapt

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.
