upstreamworks upstream works on finesse UPGRADE

Affected: >= 4.0 and <= 4.2.14 · >= 5.0 and <= 5.3

Fixed in: newer than 5.3

Safe to downgrade to: a release before 4.0

1. Check installed version

apt-cache policy upstream-works-on-finesse || rpm -q upstream-works-on-finesse || upstream-works-on-finesse --version

2. UPGRADE to newer than 5.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade upstream-works-on-finesse

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade upstream-works-on-finesse

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 4.0 (Debian / Ubuntu)

apt-cache madison upstream-works-on-finesse sudo apt install upstream-works-on-finesse=<VERSION_BEFORE_4.0> sudo apt-mark hold upstream-works-on-finesse

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

dnf --showduplicates list upstream-works-on-finesse sudo dnf downgrade upstream-works-on-finesse-<VERSION_BEFORE_4.0> sudo dnf versionlock add upstream-works-on-finesse

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.
