wecenter wecenter UPGRADE

Affected: >= 3.2.0 and <= 3.2.2

Fixed in: newer than 3.2.2

Safe to downgrade to: a release before 3.2.0

1. Check installed version

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

2. UPGRADE to newer than 3.2.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade wecenter

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 3.2.0 (Debian / Ubuntu)

apt-cache madison wecenter sudo apt install wecenter=<VERSION_BEFORE_3.2.0> sudo apt-mark hold wecenter

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

dnf --showduplicates list wecenter sudo dnf downgrade wecenter-<VERSION_BEFORE_3.2.0> sudo dnf versionlock add wecenter

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.
