getbootstrap bootstrap UPGRADE

Affected: >= 4.0.0 and < 4.1.2 · 4.0.0 alpha · 4.0.0 alpha2 · 4.0.0 alpha3 · 4.0.0 alpha4 · 4.0.0 alpha5 · 4.0.0 alpha6 · 4.0.0 beta

Fixed in: 4.1.2

Safe to downgrade to: a release before 4.0.0

1. Check installed version

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

2. UPGRADE to 4.1.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade bootstrap

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 4.0.0 (Debian / Ubuntu)

apt-cache madison bootstrap sudo apt install bootstrap=<VERSION_BEFORE_4.0.0> sudo apt-mark hold bootstrap

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

dnf --showduplicates list bootstrap sudo dnf downgrade bootstrap-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add bootstrap

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.
