Error

[Ao1Pointblank]

does not work on linux mint.

File "/usr/local/bin/a2ln", line 135
    match error.errno:
          ^
SyntaxError: invalid syntax

removing the code from lines 134-144 helps, so long as you start the server with both ports specified

You can check the Python version by using:

$ python --version
