Hi,

  communicate returns a byte sequence for Python 3, therefore the decode is required, however it seems that we got the order wrong, the decode should go before the strip. Could you change the order and see if this will work for you? I have never seen the error you report, somehow the python on tested versions was more forgiving.

Yours

Hi,

I recently used the Python scripts supplied on cat.eduroam.org for "Universität Leipzig" to configure eduroam on my Arch Linux laptop.

Although they did work out in the end, I ran into errors on my first attempt of running the scripts. Both scripts use the Popen.communicate() method to receive data from subprocesses, for example in the following line:
output = out.strip().decode('utf-8')
Since strip() is used on the variable out, it is obvious that out is of string type. However, decode(...) should not be used on strings, only on byte objects. After I removed the .decode('utf-8') on all occurences of this construction in the file, it worked out without any further errors.

Best regards

Sophie Kunze
