When I run bobarr.sh update, I get the following error:
_error getting credentials - err: exit status 1, out: `Cannot autolaunch D-Bus without X11 $DISPLAY`_

The complete log:

```

Start with the bobarr.sh update entry point and reproduce the command from the issue. Trace the Docker credential lookup that produces the D-Bus error and inspect the repository's Docker configuration; done means the update completes without this credential error.
