glpi-project glpi UPGRADE

Affected: >= 11.0.0 and < 11.0.6

Fixed in: 11.0.6

Safe to downgrade to: a release before 11.0.0

1. Check installed version

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

2. UPGRADE to 11.0.6 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade glpi

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 11.0.0 (Debian / Ubuntu)

apt-cache madison glpi sudo apt install glpi=<VERSION_BEFORE_11.0.0> sudo apt-mark hold glpi

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

dnf --showduplicates list glpi sudo dnf downgrade glpi-<VERSION_BEFORE_11.0.0> sudo dnf versionlock add glpi

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.
