osgeo geoserver UPGRADE

Affected: < 2.26.4 · >= 2.27.0 and < 2.27.3

Fixed in: 2.26.4, 2.27.3

Safe to downgrade to: a release before 2.27.0

1. Check installed version

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

2. UPGRADE to 2.26.4 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade geoserver

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 2.27.0 (Debian / Ubuntu)

apt-cache madison geoserver sudo apt install geoserver=<VERSION_BEFORE_2.27.0> sudo apt-mark hold geoserver

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

dnf --showduplicates list geoserver sudo dnf downgrade geoserver-<VERSION_BEFORE_2.27.0> sudo dnf versionlock add geoserver

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.
