zabbix zabbix UPGRADE

Affected: >= 7.0.0 and < 7.0.14 · >= 7.2.0 and < 7.2.8

Fixed in: 7.0.14, 7.2.8

Safe to downgrade to: a release before 7.0.0

1. Check installed version

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

2. UPGRADE to 7.0.14 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade zabbix

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 7.0.0 (Debian / Ubuntu)

apt-cache madison zabbix sudo apt install zabbix=<VERSION_BEFORE_7.0.0> sudo apt-mark hold zabbix

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

dnf --showduplicates list zabbix sudo dnf downgrade zabbix-<VERSION_BEFORE_7.0.0> sudo dnf versionlock add zabbix

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.
