32.5. Troubleshooting

This section covers frequent problems encountered with SCPM. Learn how they can arise and how you can solve these issues.

32.5.1. SCPM and NetworkManager

NetworkManager and SCPM share functionality. Both integrate a machine into an existing network, hiding this transaction from the user. NetworkManager works dynamically and adapts to any new environment. SCPM is used to restore defined system setups.

Using NetworkManager and SCPM in parallel does not work properly, because NetworkManager does not provide configurations that can be restored by SCPM. SCPM works exceedingly well for anyone who needs reproducible setups. Any private user constantly switching (wireless) networks should consider using NetworkManager if network setup is the only component that needs to be adjusted.

If you want to use SCPM for network configuration management, disable NetworkManager.

32.5.2. Termination During the Switch Process

Sometimes SCPM stops working during a switch procedure. This may be caused by some outside effect, such as a user abort, a power failure, or even an error in SCPM itself. If this happens, an error message stating SCPM is locked appears the next time you start SCPM. This is for system safety, because the data stored in its database may differ from the state of the system. To resolve this issue, run scpm recover. SCPM performs all missing operations of the previous run. You can also run scpm recover -b, which tries to undo all already performed operations of the previous run. If you are using the YaST profile manager, get a recover dialog on start-up that offers to perform the commands described above.
