I switched to chirp-next and I installed it with success in Linux Mint 'Vera' (21.1) and Debian 10 by downloading tar.gz file running sutup.

The only question I have now is: how to update my installation wthi the new daily releases? Is it ok download the new version running, for this setup again?

Yes, but you can also use pip to install it instead of setup, and pip has uninstall and upgrade routines.

We probably need to do some work updating the site for chirp-next and linux.
