still seeing this error when trying to start up the local server: https://pastebin.com/bP4y8M9f
EDIT: After manually installing python-async_generator and python-aiofiles as mentioned by @DragonX256 gns3server runs as expected. THANK YOU!!

@daemon. I just tested it now and worked fine. Double check dependencies or try to reinstall

Still something is broken... running the server in local computer and not in any sort or form of VM. The gns3server is not starting and gives this output:

not quite sure, but seems it's starting server "None" and then tries to connect to "local" and doesn't find it by this name (because it started "None", not "local"?) or am I reading something something wrong there? Might be gns3-server itself bug -- which i reported just in case. Downgraded to 2.1.21 and it properly starts the server in 127.0.0.1 instead of the "None".

Thank you @buzo. You're the best!

Fixed – sorry for the delay, I am currently on vacation.

alexanderp: A question is not an error. You should answer “yes”, or does this break anything else?
See comments below for why this dependency changed.

Upstream has split development of the major versions 2 and 3. This package will keep tracking the latest version. If you prefer version 2, there is now a separate package gns3-server-2.
