Timeline

techtime user management UPGRADE
Affected: >= 2.0.0 and <= 2.15.24
Fixed in: newer than 2.15.24
Safe to downgrade to: a release before 2.0.0
1. Check installed version
apt-cache policy user-management || rpm -q user-management || user-management --version
2. UPGRADE to newer than 2.15.24 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade user-management
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade user-management
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 2.0.0 (Debian / Ubuntu)
apt-cache madison user-management sudo apt install user-management=<VERSION_BEFORE_2.0.0> sudo apt-mark hold user-management
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list user-management sudo dnf downgrade user-management-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add user-management
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.
