Trixy Install problems

I have downloaded and flashed Debian Trixy Linuxcnc from the download page twice now. And every time I try to install, it gets stuck at configuring the sources. I do not think it is a network problem because when I run the live instance, I can browse the internet. Please can someone offer a solution, or tell me where I can download the Bookworm version, which I know works.
Thanks

You should still be able to install it without internet or broken installer but apt will point to the CD only. I think it will get confused in some locales because the installer defaults the mirror and in some countries, this fails.

There is an issue with Debian Live which we use for the installer. Debian moved to using debian deb822 format for sources. This places the sources in /etc/apt/sources.list.d/debian.sources instead of /etc/apt/sources.list

Debian live has not caught up with this change.
so assuming you do get a bootable system, what does
cat /etc/apt/sources.list display? is it just the CD or DVD?

You could create Debian.sources in the folder above that contains
Then delete /etc/apt/sources.list
and then type sudo apt update
 

Thanks for the explanation, but I still don't know how to install the thing. I have tried all the options at that stage of the process, but it just goes round in an endless loop of errors. If I tell the installer I am in USA might that work?
