lat bit of the trace

… while calling the 'import' builtin

Looking into it more verbose, there is a netrc error. Just trying with curl, yields:

❯ curl -n --netrc-file /run/agenix/attic-pull https://github.com/nix-community/home-manager/archive/8cf9cb2ee78aa129e5b8220135a511a2be254c0c.tar.gz
curl: (26) .netrc parser error

So this seems to be a duplicate of #356114
