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 33.00 (Debian / Ubuntu)

apt-cache madison studio-5000-logix-designer sudo apt install studio-5000-logix-designer=<VERSION_BEFORE_33.00> sudo apt-mark hold studio-5000-logix-designer

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list studio-5000-logix-designer sudo dnf downgrade studio-5000-logix-designer-<VERSION_BEFORE_33.00> sudo dnf versionlock add studio-5000-logix-designer

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.
