It could be that ./guix.de.texi already exists and is read-only, or that
“.” is read-only.

Ah yes, that looks like a problem: “doc”, which is taken straight from
the checkout, normally does not contain *.LANG.texi; those files are not
checked in.

Could it be that ~/.cache/guix/checkouts contains a non-pristine
checkout of Guix with that extra file?

Thanks for investigating!
