elastic kibana UPGRADE

Affected: >= 9.1.0 and < 9.4.5

Fixed in: 9.4.5

Safe to downgrade to: a release before 9.1.0

1. Check installed version

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

2. UPGRADE to 9.4.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade kibana

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 9.1.0 (Debian / Ubuntu)

apt-cache madison kibana sudo apt install kibana=<VERSION_BEFORE_9.1.0> sudo apt-mark hold kibana

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

dnf --showduplicates list kibana sudo dnf downgrade kibana-<VERSION_BEFORE_9.1.0> sudo dnf versionlock add kibana

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.
