lasuite docs UPGRADE

Affected: >= 3.8.0 and < 4.3.0

Fixed in: 4.3.0

Safe to downgrade to: a release before 3.8.0

1. Check installed version

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

2. UPGRADE to 4.3.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade docs

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 3.8.0 (Debian / Ubuntu)

apt-cache madison docs sudo apt install docs=<VERSION_BEFORE_3.8.0> sudo apt-mark hold docs

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

dnf --showduplicates list docs sudo dnf downgrade docs-<VERSION_BEFORE_3.8.0> sudo dnf versionlock add docs

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.
