siemens tecnomatix UPGRADE

Affected: >= 2201 and < 2201.0008 · >= 2302 and < 2302.0002

Fixed in: 2201.0008, 2302.0002

Safe to downgrade to: a release before 2201

1. Check installed version

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

2. UPGRADE to 2201.0008 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade tecnomatix

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade tecnomatix

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 2201 (Debian / Ubuntu)

apt-cache madison tecnomatix sudo apt install tecnomatix=<VERSION_BEFORE_2201> sudo apt-mark hold tecnomatix

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

dnf --showduplicates list tecnomatix sudo dnf downgrade tecnomatix-<VERSION_BEFORE_2201> sudo dnf versionlock add tecnomatix

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.
