scratchstatus scratchtools UPGRADE

Affected: >= 2.4.0 and < 2.5.2

Fixed in: 2.5.2

Safe to downgrade to: a release before 2.4.0

1. Check installed version

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

2. UPGRADE to 2.5.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade scratchtools

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 2.4.0 (Debian / Ubuntu)

apt-cache madison scratchtools sudo apt install scratchtools=<VERSION_BEFORE_2.4.0> sudo apt-mark hold scratchtools

dnf --showduplicates list scratchtools sudo dnf downgrade scratchtools-<VERSION_BEFORE_2.4.0> sudo dnf versionlock add scratchtools

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.
