exhibitor project exhibitor UPGRADE

Affected: >= 1.0.9 and <= 1.7.1

Fixed in: newer than 1.7.1

Safe to downgrade to: a release before 1.0.9

1. Check installed version

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

2. UPGRADE to newer than 1.7.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade exhibitor

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 1.0.9 (Debian / Ubuntu)

apt-cache madison exhibitor sudo apt install exhibitor=<VERSION_BEFORE_1.0.9> sudo apt-mark hold exhibitor

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

dnf --showduplicates list exhibitor sudo dnf downgrade exhibitor-<VERSION_BEFORE_1.0.9> sudo dnf versionlock add exhibitor

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.
