Hi,
I've just installed the new version of vncdotool and get this error when trying to capture screen :

  File "/usr/local/lib/python3.6/site-packages/vncdotool/rfb.py", line 835, in setKey
    if bsrc & (1 << i):
builtins.TypeError: unsupported operand type(s) for &: 'str' and 'int'

The complete listing is at the end of this message.

04/17/2020 EDIT : I remove vncdotool 1.0.0 and rebuild 0.12 version : it works fine. I retry with 1.0.0 (from pip), I get the error.

Thanks for your help.
Alain

Hello there. Is there an official workaround or something like that for this case? It's still valid, at least for v1.0.0 .

alex-romanov commented

Nevermind.
For folks who struggle with the same issue - just use a latest stable version instead of 1.0.0 from pip repo, in my case it's 0.12.0 which worked like a charm.
