Hi,

Trying to answer to this message [1], I notice something unexpected for
me.  I read from the manual:

--8<---------------cut here---------------start------------->8---
-- Procedure: url-fetch url hash-algo hash [name] [#:executable? #f]
     Return a fixed-output derivation that fetches data from URL (a
     string, or a list of strings denoting alternate URLs), which is
     expected to have hash HASH of type HASH-ALGO (a symbol).  By
     default, the file name is the base name of URL; optionally, NAME
     can specify a different file name.  When EXECUTABLE? is true, make
     the downloaded file executable.

     When one of the URL starts with ‘mirror://’, then its host part is
     interpreted as the name of a mirror scheme, taken from
     ‘%mirror-file’.

     Alternatively, when URL starts with ‘file://’, return the
     corresponding file name in the store.
--8<---------------cut here---------------end--------------->8---

Therefore, I do:

--8<---------------cut here---------------start------------->8---
(define-module (pkg)
  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (gnu packages pdf)
  #:use-module (gnu packages gnome))

(define-public zathura-custom
  (package
   (inherit zathura)
   (name "zathura-custom")
   (version "4.0")
   (source
    (origin
     (method url-fetch)
     (uri
      ;"https://pwmt.org/projects/zathura/download/zathura-0.5.2.tar.xz"
      "file:///tmp/zathura-custom/zathura-mine.tar.xz"
      )
     (sha256
      (base32
       "0000000000000000000000000000000000000000000000000000"))))))
--8<---------------cut here---------------end--------------->8---

And then:

--8<---------------cut here---------------start------------->8---
$ guix build -L /tmp/zathura-custom zathura-custom -S -d

1: [TIL] guix doesn't check hash when uri starts with file:///
