ethyca fides UPGRADE

Affected: >= 2.19.0 and < 2.44.0

Fixed in: 2.44.0

Safe to downgrade to: a release before 2.19.0

1. Check installed version

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

2. UPGRADE to 2.44.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 2.19.0 (Debian / Ubuntu)

apt-cache madison fides sudo apt install fides=<VERSION_BEFORE_2.19.0> sudo apt-mark hold fides

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

dnf --showduplicates list fides sudo dnf downgrade fides-<VERSION_BEFORE_2.19.0> sudo dnf versionlock add fides

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.
