catt errors on Python 3.10 (Arch)

[weisserd]

When trying any subcommand with catt (e.g. scan or cast_site) I get the following error:

$ catt scan

The versions used are:

• Python 3.10.1
• catt v0.12.1, Zaniest Zapper.
• OS ManjaroLinux - catt installed from aur - https://aur.archlinux.org/packages/catt/

[weisserd]

Looks similar to the already closed issue #349

[skorokithakis]

Yes, sounds like the same bug, can you try the latest version and see if that solves it?

[weisserd]

When switching to catt-git (https://aur.archlinux.org/packages/catt-git) it reports the following version:

• catt v0.12.5, Zaniest Zapper.

However the problem still exists - its the same stacktrace as above

[skorokithakis]

Hmm, what's the PyChromecast version?

[weisserd]

It's aur/python-pychromecast 10.2.2-1

[skorokithakis]

That's the wrong version, please either use one of the supported methods of installation or file a bug with AUR.

@skorokithakis I am having the same issue. What is the required python-pychromecast version?
