N: Skipping acquire of configured file 'main/binary-armhf/Packages' as repository 'https://paulcarroty.gitlab.io/vscodium-deb-rpm-repo/debs vscodium InRelease' doesn't support architecture 'armhf' N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'https://paulcarroty.gitlab.io/vscodium-deb-rpm-repo/debs vscodium InRelease' doesn't support architecture 'i386'
