I am trying to updating this package on openSUSE RPM repository. Some of the tests are failing because the code cannot access /var/user in the container environment:

Any idea how to fix it?

[alexandrevicenzi]

Adding something like the following to DummyVPNConnection might fix the issue.

def __base_path(self):
    return "/tmp/some/path/"

The problem is that OBS does not allow access to certain things outside the build directory, so a patch needs to be added to the package.

I did not test this, but I can test it later and submit an SR.
