Overall problem: a certain test of a certain package fails spuriously for random builds.
The test does nothing else than deleting a file, that was created before. It fails, since for some reason, the file doesn't exist.
Are you sure the test is race-free? AFAIU, the file is created by some subprocess, which may take some time to start and create the file. Note that the file is confirmed to not exist before it is tried to be removed.
I can see a lot of other races in the testsuite.
