It should be fixed now, could you try again, please?

Hi @N-Mi

I'm not a Debian user and I don't know how to add PPAs there, but "trixie" is a Debian release, not an Ubuntu release, so it is expected to be not found.

You'd need to check online how to add PPAs to Debian, it looks like you missed a step.
