craftycontrol crafty controller UPGRADE
Affected: >= 4.4.0 and < 4.10.8
Fixed in: 4.10.8
Safe to downgrade to: a release before 4.4.0
1. Check installed version
apt-cache policy crafty-controller || rpm -q crafty-controller || crafty-controller --version
2. UPGRADE to 4.10.8 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade crafty-controller
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade crafty-controller
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 4.4.0 (Debian / Ubuntu)
apt-cache madison crafty-controller
sudo apt install crafty-controller=<VERSION_BEFORE_4.4.0>
sudo apt-mark hold crafty-controller
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list crafty-controller
sudo dnf downgrade crafty-controller-<VERSION_BEFORE_4.4.0>
sudo dnf versionlock add crafty-controller
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.
