apache pekko management UPGRADE

Affected: >= 1.0.0 and <= 1.1.1

Fixed in: newer than 1.1.1

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy pekko-management || rpm -q pekko-management || pekko-management --version

2. UPGRADE to newer than 1.1.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pekko-management

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pekko-management

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 1.0.0 (Debian / Ubuntu)

apt-cache madison pekko-management sudo apt install pekko-management=<VERSION_BEFORE_1.0.0> sudo apt-mark hold pekko-management

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

dnf --showduplicates list pekko-management sudo dnf downgrade pekko-management-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add pekko-management

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.
