lunary lunary UPGRADE

Affected: >= 1.2.7 and < 1.4.3

Fixed in: 1.4.3

Safe to downgrade to: a release before 1.2.7

Note

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

apt-cache madison lunary sudo apt install lunary=<VERSION_BEFORE_1.2.7> sudo apt-mark hold lunary

dnf --showduplicates list lunary sudo dnf downgrade lunary-<VERSION_BEFORE_1.2.7> sudo dnf versionlock add lunary

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.
