I took a stab at improving the error message (see the linked PR)
$ ./python -c 'import tarfile; tarfile.open("Lib/test/testtar.tar.xz")'
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/home/asottile/workspace/cpython/Lib/tarfile.py", line 1620, in open
raise ReadError(f"file could not be opened successfully:\n{error_msgs}")
tarfile.ReadError: file could not be opened successfully:
- method gz: ReadError('not a gzip file')
- method bz2: CompressionError('bz2 module is not available')
- method xz: CompressionError('lzma module is not available')
- method tar: ReadError('truncated header')
