ca unified infrastructure management DOWNGRADE

Affected: 8.4.7 · 8.5 · 8.5.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 8.4.7

1. Check installed version

apt-cache policy unified-infrastructure-management || rpm -q unified-infrastructure-management || unified-infrastructure-management --version

2. No fixed release: DOWNGRADE to a release before 8.4.7 (Debian / Ubuntu)

apt-cache madison unified-infrastructure-management sudo apt install unified-infrastructure-management=<VERSION_BEFORE_8.4.7> sudo apt-mark hold unified-infrastructure-management

dnf --showduplicates list unified-infrastructure-management sudo dnf downgrade unified-infrastructure-management-<VERSION_BEFORE_8.4.7> sudo dnf versionlock add unified-infrastructure-management

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.
