ladon project ladon UPGRADE

Affected: >= 0.6.1 and <= 0.9.40

Fixed in: newer than 0.9.40

Safe to downgrade to: a release before 0.6.1

1. Check installed version

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

2. UPGRADE to newer than 0.9.40 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ladon

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 0.6.1 (Debian / Ubuntu)

apt-cache madison ladon sudo apt install ladon=<VERSION_BEFORE_0.6.1> sudo apt-mark hold ladon

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

dnf --showduplicates list ladon sudo dnf downgrade ladon-<VERSION_BEFORE_0.6.1> sudo dnf versionlock add ladon

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.
