Udocker not working with python 3

[alpegon]

Hi, when executing udocker in a python 3 environment I get the following error:

Traceback (most recent call last):
  File "udocker", line 5844, in <module>
    sys.exit(Main().start())
  File "udocker", line 5757, in __init__
    if not self.cmdp.parse(sys.argv):
  File "udocker", line 5618, in parse
    if arg[0] in string.letters:
AttributeError: module 'string' has no attribute 'letters'

Looks like an incompatibility with the python libraries.
Are you planning on supporting python 3?

Thanks

work ongoing on devel3 branch, largely done

+1!

Is there any documentation on the devel3 branch as udocker.py doesnt exist? Most of our systems do not have python2 at all so this has been a show stopper since we can no longer use udocker until python3 is supported.

hi
pre-release with instructions

Thanks for the Python 3 progress. As a reminder it will be possible and perhaps common for users of the next Debian release (and other Linux distributions) to have Python 3 but no Python 2.

pre release 1.2.9 soon to be released, considered solved
