With apt-get update I got the error message:
Reading package lists... done
N: Skipping acquire of configured file "main/binary-i386/Packages"
as repository "https://repo.ckvsoft.at/ckvsoft jammy-ckvsoft-stable InRelease" doesn't support architecture 'i386'.
I have been looking in the apt directory but there is no File with "main/binary-i386/Packages". This is a newly build system that is fully 64-bit.
I found that Google Chrome could be responsible, but there is no repository that points to Google.
