druide antidote UPGRADE

Affected: >= 8.0 and < 8.05.2287 · >= 9.0 and < 9.5.3937 · >= 10.0 and < 10.1.2147

Fixed in: 8.05.2287, 9.5.3937, 10.1.2147

Safe to downgrade to: a release before 8.0

1. Check installed version

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

2. UPGRADE to 8.05.2287 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade antidote

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 8.0 (Debian / Ubuntu)

apt-cache madison antidote sudo apt install antidote=<VERSION_BEFORE_8.0> sudo apt-mark hold antidote

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

dnf --showduplicates list antidote sudo dnf downgrade antidote-<VERSION_BEFORE_8.0> sudo dnf versionlock add antidote

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.
