hcltech domino leap UPGRADE

Affected: >= 1.1 and < 1.1.3

Fixed in: 1.1.3

Safe to downgrade to: a release before 1.1

1. Check installed version

apt-cache policy domino-leap || rpm -q domino-leap || domino-leap --version

2. UPGRADE to 1.1.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade domino-leap

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 1.1 (Debian / Ubuntu)

apt-cache madison domino-leap sudo apt install domino-leap=<VERSION_BEFORE_1.1> sudo apt-mark hold domino-leap

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

dnf --showduplicates list domino-leap sudo dnf downgrade domino-leap-<VERSION_BEFORE_1.1> sudo dnf versionlock add domino-leap

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.
