ruifang-tech rebuild UPGRADE

Affected: >= 3.9.0 and <= 3.9.3

Fixed in: newer than 3.9.3

Safe to downgrade to: a release before 3.9.0

1. Check installed version

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

2. UPGRADE to newer than 3.9.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade rebuild

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 3.9.0 (Debian / Ubuntu)

apt-cache madison rebuild sudo apt install rebuild=<VERSION_BEFORE_3.9.0> sudo apt-mark hold rebuild

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

dnf --showduplicates list rebuild sudo dnf downgrade rebuild-<VERSION_BEFORE_3.9.0> sudo dnf versionlock add rebuild

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.
