You're using python 3.11 archinstall requires 3.10

You're using python 3.11 archinstall requires 3.10

I apologise if this is a bad question, but can you guide me on how to use python 3.10 instead of 3.11?

[Torxed]

v2.5.6 should be built against Python 3.11 so as long as the May ISO uses Py3.11 we should be good. Best option is to pacman -Syu atm

[svartkanin]

Ohh I wasn't aware of the upgrade on the iso

I am getting this error after building the iso directly from the build_iso script provided in the repo. Am I doing anything wrong?

[svartkanin]

Gotcha, I'll have a look qt it, I don't think it's compatible with python 3.11 just yet

Thank you!

Just verified, it's still Python 3.10 on the ISO, so upgrading archinstall might cause issues. I say might because the entrypoint in /usr/bin/archinstal is version agnostic, but the way Python handles plugins and pkg_resources might cause issues anyway.

I unfortunately only have access to a weird wifi setup right now so can't get networking up and running to do pacman -Syu in the ISO.

But May iso contains:

• Python 3.10
• archinstall 2.5.5

I would say that they have to do a full upgrade to get all the hooks right.

[svartkanin]

Alright that's good, I'll run it through 3.11 over the weekend and see if I can get it to work.
