Kevin Funk added the comment: It's Python 3.6 from CentOS 6. In my particular case I'm lacking the lzma module. But for figuring that out I had to add the explicit modes to the `tarfile.open` calls in my Python script. -- ___ Pyth

Kevin Funk added the comment: I just ran into this, under Python 3.6. IMHO, the error message should be improved, even when the mode was not passed explicitly. Can someone reopen this? -- nosy: +kfunk ___ Python tracker <https://bugs.python.
