openrobotics robot operating system DOWNGRADE

Affected: 2 humble · 2 iron

Fixed in: no fixed release known

Safe to downgrade to: a release before 2

1. Check installed version

apt-cache policy robot-operating-system || rpm -q robot-operating-system || robot-operating-system --version

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

apt-cache madison robot-operating-system sudo apt install robot-operating-system=<VERSION_BEFORE_2> sudo apt-mark hold robot-operating-system

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

dnf --showduplicates list robot-operating-system sudo dnf downgrade robot-operating-system-<VERSION_BEFORE_2> sudo dnf versionlock add robot-operating-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.
