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 6.0.0 (Debian / Ubuntu)

apt-cache madison simple-realtime-server sudo apt install simple-realtime-server=<VERSION_BEFORE_6.0.0> sudo apt-mark hold simple-realtime-server

dnf --showduplicates list simple-realtime-server sudo dnf downgrade simple-realtime-server-<VERSION_BEFORE_6.0.0> sudo dnf versionlock add simple-realtime-server

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.
