CHIRP

hello,
I've just changed my old UBUNTU OS to DEBIAN 12. On gnome-software there is a CHIRP version number 3.2.2, It seems an old version but I'm not sure.

I tried your advises :"2.2 For distros with the managed flag (Ubuntu 23.04, Debian 11 and later)"
but let me show you the results :
didier@debian:~$ pipx install --system-site-packages ./chirp-20230509-py3-none-any.whl
Unable to parse package spec: ./chirp-20230509-py3-none-any.whl
or
*didier@debian:~$ pipx install --system-site-packages ./chirp-20240322-py3-none-any.whl
Unable to parse package spec: ./chirp-20240322-py3-none-any.whl
*

Could you help me to install et to take the daily versions ? I tried a flatpak version, but it does'not work any more.
Best Regards
Didier
