Thank you for the report. If you update hex_decode() in /usr/lib/python3/dist-packages/ufw/util.py to use this:
return binascii.unhexlify('%2s' % h).decode("utf-8") instead of: return binascii.unhexlify(h).decode("utf-8") Does it resolve the issue for you? -- Email: ja...@strandboge.com IRC: jdstrand
