Safe to downgrade to: a release before 10.2
1. Check installed version
apt-cache policy comos || rpm -q comos || comos --version
2. UPGRADE to 10.3.3.1.45 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade comos
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade comos
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 10.2 (Debian / Ubuntu)
apt-cache madison comos
sudo apt install comos=<VERSION_BEFORE_10.2>
sudo apt-mark hold comos
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list comos
sudo dnf downgrade comos-<VERSION_BEFORE_10.2>
sudo dnf versionlock add comos
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.
