newforma project center DOWNGRADE

Affected: 2024.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 2024.3

1. Check installed version

apt-cache policy project-center || rpm -q project-center || project-center --version

2. No fixed release: DOWNGRADE to a release before 2024.3 (Debian / Ubuntu)

apt-cache madison project-center sudo apt install project-center=<VERSION_BEFORE_2024.3> sudo apt-mark hold project-center

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

dnf --showduplicates list project-center sudo dnf downgrade project-center-<VERSION_BEFORE_2024.3> sudo dnf versionlock add project-center

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.
