ninjaframework ninja DOWNGRADE

Affected: 7.0.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.0.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 7.0.0 (Debian / Ubuntu)

apt-cache madison ninja sudo apt install ninja=<VERSION_BEFORE_7.0.0> sudo apt-mark hold ninja

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

dnf --showduplicates list ninja sudo dnf downgrade ninja-<VERSION_BEFORE_7.0.0> sudo dnf versionlock add ninja

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.
