robocode robocode DOWNGRADE

Affected: 1.9.3.6

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.9.3.6

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.9.3.6 (Debian / Ubuntu)

apt-cache madison robocode sudo apt install robocode=<VERSION_BEFORE_1.9.3.6> sudo apt-mark hold robocode

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list robocode sudo dnf downgrade robocode-<VERSION_BEFORE_1.9.3.6> sudo dnf versionlock add robocode

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.
