4cstrategies exonaut UPGRADE

Affected: < 21.6.2.1-1 · >= 22.0 and < 22.4

Fixed in: 21.6.2.1-1, 22.4

Safe to downgrade to: a release before 22.0

1. Check installed version

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

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 22.0 (Debian / Ubuntu)

apt-cache madison exonaut sudo apt install exonaut=<VERSION_BEFORE_22.0> sudo apt-mark hold exonaut

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

dnf --showduplicates list exonaut sudo dnf downgrade exonaut-<VERSION_BEFORE_22.0> sudo dnf versionlock add exonaut

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.
