singularity software team factor DOWNGRADE

Affected: 1.25 · 1.25m

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.25

1. Check installed version

apt-cache policy team-factor || rpm -q team-factor || team-factor --version

2. No fixed release: DOWNGRADE to a release before 1.25 (Debian / Ubuntu)

apt-cache madison team-factor sudo apt install team-factor=<VERSION_BEFORE_1.25> sudo apt-mark hold team-factor

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

dnf --showduplicates list team-factor sudo dnf downgrade team-factor-<VERSION_BEFORE_1.25> sudo dnf versionlock add team-factor

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.
