Yeah, I've noticed the issue. It's a combination of multiple things. The partition not being detected is an issue with kpmcore not working in unstable after some newer commits. Would be fixed by #191822.

Some issues with locales being inputted incorrectly would be fixed by #193041.

Having the same issue with nixos-plasma5-22.11pre424902.09326850228-x86_64-linux.iso 2022-11-10

Both PRs were merged and have reached nixos-unstable.

• kpmcore: patch trustedprefixes #191822
• calamares: fix errors and update modules #193041

Can you retry with yesterdays ISO? https://hydra.nixos.org/build/198722895

Have tried the ISO. Issue is resolved now. Thanks for the fix.
