ibm engineering systems design rhapsody DOWNGRADE

Affected: 9.0.2 · 10.0 · 10.0.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 9.0.2

1. Check installed version

apt-cache policy engineering-systems-design-rhapsody || rpm -q engineering-systems-design-rhapsody || engineering-systems-design-rhapsody --version

2. No fixed release: DOWNGRADE to a release before 9.0.2 (Debian / Ubuntu)

apt-cache madison engineering-systems-design-rhapsody sudo apt install engineering-systems-design-rhapsody=<VERSION_BEFORE_9.0.2> sudo apt-mark hold engineering-systems-design-rhapsody

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

dnf --showduplicates list engineering-systems-design-rhapsody sudo dnf downgrade engineering-systems-design-rhapsody-<VERSION_BEFORE_9.0.2> sudo dnf versionlock add engineering-systems-design-rhapsody

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.
