1. Check installed version

apt-cache policy buk-ts-g-gas-station-automation-system || rpm -q buk-ts-g-gas-station-automation-system || buk-ts-g-gas-station-automation-system --version

2. UPGRADE to 2.10.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade buk-ts-g-gas-station-automation-system

dnf --showduplicates list buk-ts-g-gas-station-automation-system sudo dnf downgrade buk-ts-g-gas-station-automation-system-<VERSION_BEFORE_2.9.1> sudo dnf versionlock add buk-ts-g-gas-station-automation-system

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.
