Safe to downgrade to: a release before 2.31.0

1. Check installed version

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

2. UPGRADE to 2.30.8 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade git

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade git

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.31.0 (Debian / Ubuntu)

apt-cache madison git sudo apt install git=<VERSION_BEFORE_2.31.0> sudo apt-mark hold git

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list git sudo dnf downgrade git-<VERSION_BEFORE_2.31.0> sudo dnf versionlock add git

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.
