The “Warning: RPMDB altered outside of yum” error message appears when the RPM database gets modified by a process other than the yum package manager. This usually occurs when you install or remove packages using the ‘rpm’ command directly, which can lead to inconsistencies between the RPM database and yum’s knowledge of installed packages. Fixing this issue is essential to maintain a healthy and functional package management system on your Linux server.
