pexip pexip infinity UPGRADE

Affected: < 38.2 · >= 39.0 and <= 39.1 · 40.0

Fixed in: 38.2

Safe to downgrade to: a release before 39.0

1. Check installed version

apt-cache policy pexip-infinity || rpm -q pexip-infinity || pexip-infinity --version

2. UPGRADE to 38.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pexip-infinity

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pexip-infinity

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 39.0 (Debian / Ubuntu)

apt-cache madison pexip-infinity sudo apt install pexip-infinity=<VERSION_BEFORE_39.0> sudo apt-mark hold pexip-infinity

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

dnf --showduplicates list pexip-infinity sudo dnf downgrade pexip-infinity-<VERSION_BEFORE_39.0> sudo dnf versionlock add pexip-infinity

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.
