Timeline

suse rancher UPGRADE
Affected: >= 2.6.7 and < 2.6.13 · >= 2.7.0 and < 2.7.4
Fixed in: 2.6.13, 2.7.4
Safe to downgrade to: a release before 2.6.7
1. Check installed version
apt-cache policy rancher || rpm -q rancher || rancher --version
2. UPGRADE to 2.6.13 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade rancher
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade rancher
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 2.6.7 (Debian / Ubuntu)
apt-cache madison rancher sudo apt install rancher=<VERSION_BEFORE_2.6.7> sudo apt-mark hold rancher
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list rancher sudo dnf downgrade rancher-<VERSION_BEFORE_2.6.7> sudo dnf versionlock add rancher
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.
