When trying to run a plan test with a source type git_archive like motionmark the following error happens on a Debian Linux box:

$ Tools/Scripts/run-benchmark  --plan motionmark

subprocess.CalledProcessError: Command '['tar', 'zxvf', '/tmp/tmp7pcm6qqk/temp.tar', '-C', '/tmp/tmp7pcm6qqk/extract']' returned non-zero exit status 2.


The error is caused because when passing the flag 'z' to the GNU tar program the input should be in gzip format, but it is in plain tar format
