root3 support app UPGRADE

Affected: >= 2.3.1 and < 2.5.1

Fixed in: 2.5.1

Safe to downgrade to: a release before 2.3.1

1. Check installed version

apt-cache policy support-app || rpm -q support-app || support-app --version

2. UPGRADE to 2.5.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade support-app

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade support-app

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 2.3.1 (Debian / Ubuntu)

apt-cache madison support-app sudo apt install support-app=<VERSION_BEFORE_2.3.1> sudo apt-mark hold support-app

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

dnf --showduplicates list support-app sudo dnf downgrade support-app-<VERSION_BEFORE_2.3.1> sudo dnf versionlock add support-app

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.
