The patch applies cleanly:

    $ g am ~/Downloads/66409-0.mbox
    Applying: gnu: linux-libre: Update to 6.5.6.
    $ g l -2 --oneline --no-decorate 
    a2f741df37 gnu: linux-libre: Update to 6.5.6.
    f4e8baf380 gnu: nyxt: Update to 3.9.0.

Locally it builds well, verified by running:

    $ guix shell -D guix -- ./pre-inst-env guix build linux-libre

The failure did happen in building derivation of guix-cli, and it was due to a
segmentation fault:

I do not know enough yet to debug further.
