pukiwiki pukiwiki UPGRADE

Affected: >= 1.3.1 and < 1.5.4

Fixed in: 1.5.4

Safe to downgrade to: a release before 1.3.1

1. Check installed version

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

2. UPGRADE to 1.5.4 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 1.3.1 (Debian / Ubuntu)

apt-cache madison pukiwiki sudo apt install pukiwiki=<VERSION_BEFORE_1.3.1> sudo apt-mark hold pukiwiki

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

dnf --showduplicates list pukiwiki sudo dnf downgrade pukiwiki-<VERSION_BEFORE_1.3.1> sudo dnf versionlock add pukiwiki

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.
