Hi all: After upgrading ecosystem to 4.0.The python is 3.10.4,when hp-setup,the "SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats.".How can i do?or how can I install python 3.82 online?

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

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.

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
        500 http://packages.openstlinux.st.com/4.0 kirkstone/updates armhf Packages
     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
 
HP Linux Imaging and Printing System (ver. 3.19.12)
