onevision workspace DOWNGRADE

Affected: 22.1 · 22.2 · 23.1

Fixed in: no fixed release known

1. Check installed version

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

dnf --showduplicates list workspace sudo dnf downgrade workspace-<VERSION_BEFORE_22.1> sudo dnf versionlock add workspace

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.
