sciencelogic sl1 UPGRADE

Affected: >= 10.1.0 and < 12.1.3 · >= 12.2.0 and < 12.2.3

Fixed in: 12.1.3, 12.2.3

Safe to downgrade to: a release before 10.1.0

1. Check installed version

apt-cache policy sl1 || rpm -q sl1 || sl1 --version

2. UPGRADE to 12.1.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade sl1

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sl1

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 10.1.0 (Debian / Ubuntu)

apt-cache madison sl1 sudo apt install sl1=<VERSION_BEFORE_10.1.0> sudo apt-mark hold sl1

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

dnf --showduplicates list sl1 sudo dnf downgrade sl1-<VERSION_BEFORE_10.1.0> sudo dnf versionlock add sl1

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.
