UBOS is in a "degraded" state

/docs/users/faq-howto-troubleshooting/error-degraded/

To figure out what’s going on, execute:

% sudo ubos-admin status --problems

This should give you a description of which service(s) have failed. Let’s say it is foo.service (there is no such service as foo.service: place foo with the name of the service that failed on your Device.

Try to restart the service:
```
% sudo systemctl restart foo.service
```
After a little while, check whether that fixed it by running sudo ubos-admin status --problems again. If not, read on.
To figure out why foo.service fails to start, ask for its log:
```
% sudo journalctl -u foo.service
```
If that brings up way too much information, you can limit the output to, say, the last 10 minutes, by invoking it as follows:
```
% sudo journalctl -u foo.service --since -10m
```

That should give you enough information to figure out what the problem is.
