Safe to downgrade to: a release before 2024.2.33606

1. Check installed version

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

2. UPGRADE to 2024.2.148429 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade hub

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 2024.2.33606 (Debian / Ubuntu)

apt-cache madison hub sudo apt install hub=<VERSION_BEFORE_2024.2.33606> sudo apt-mark hold hub

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

dnf --showduplicates list hub sudo dnf downgrade hub-<VERSION_BEFORE_2024.2.33606> sudo dnf versionlock add hub

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.
