maku maku-boot UPGRADE

Affected: >= 1.3.0 and <= 2.2.0

Fixed in: newer than 2.2.0

Safe to downgrade to: a release before 1.3.0

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 1.3.0 (Debian / Ubuntu)

apt-cache madison maku-boot sudo apt install maku-boot=<VERSION_BEFORE_1.3.0> sudo apt-mark hold maku-boot

dnf --showduplicates list maku-boot sudo dnf downgrade maku-boot-<VERSION_BEFORE_1.3.0> sudo dnf versionlock add maku-boot

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.
