Hplip is only 3.19.12, and there is no higher version.

    Hi @zxiao.4​ 

    An updated package hplip 3.19.12-r2 is available from «apt-get install» command:

    root@stm32mp1:~# apt-cache policy hplip
hplip:
 Installed: (none)
 Candidate: 3.19.12-r2
 Version table:
 3.19.12-r2 500

 3.19.12-r0 500
 500 http://packages.openstlinux.st.com/4.0 kirkstone/untested armhf Packages

    After installing hplip (and python3-dbus too) with the command:

    root@stm32mp1:~# apt-get install hplip python3-dbus

    hp-setup does no longer generate the error you reported earlier:

    root@stm32mp1:~# hp-setup

    Hello @zxiao.4​ 

    Indeed, there is a break introduced with Python 3.10 as mentioned here: https://bugs.python.org/issue40943

    related to this Python PEP published here: https://peps.python.org/pep-0353/

    From what I can see, there is a fix to support Python 3.10 in last hplip versions.

    I will try to bring a patch to the hplip package and will keep you posted.

    Anyway, to reply to your question, there is no easy way to downgrade Python to python3.8 as provided in the ecosystem 3.1. Without any fix, the best way would be to come back to ecosystem 3.1 instead of ecosystem 4.0.

    Best regards,
