When I run unit tests by 'tox -e py38', 4 tests constantly fail.
Looking at the traceback it seems the interface manipulation is executed and rejected because the process is triggered by non-root user.
It's not reasonable to require root priviledge to run unit tests. Also these operations are concerning because it would result in system level change.
We should mock these operations in unit tests.
