frangoteam fuxa DOWNGRADE

Affected: 1.2.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.2.7

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.2.7 (Debian / Ubuntu)

apt-cache madison fuxa sudo apt install fuxa=<VERSION_BEFORE_1.2.7> sudo apt-mark hold fuxa

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list fuxa sudo dnf downgrade fuxa-<VERSION_BEFORE_1.2.7> sudo dnf versionlock add fuxa

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.
