Subject: Nonexistent Git commit referenced from current Guix package
Date: Thu, 9 Jul 2020 17:38:13 -0400

The current Guix package points to a Git commit that does not exist,
which breaks the ability to build the package.

The current package version is '1.1.0-16.d3eee3c'.

That commit d3eee3c [0] is the commit that updated the Guix package
previously, to '1.1.0-15.03deb1e'.

However, there is no commit 03deb1e [1].

I'm not sure exactly which contexts will hit this bug, but somebody on
IRC had trouble:

http://logs.guix.gnu.org/guix/2020-07-09.log#232819

Specifically, while trying to build

'/gnu/store/igf09dzbik8id1bh9f0lahib6716fk81-guix-1.1.0-15.03deb1e-checkout',

... it failed with:

"fatal: reference is not a tree: 03deb1e891b8a8b21888e5e047017fd6a3ea7a5f".

Yes, it was a mistake, and that’s why 1.1.0-16 was committed minutes
later:

  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=b919d4048e72f8e5740606cdb3dac0592de21f36

Someone who encounters this bug should run ‘guix pull’.

HTH!

If you create an installer with todays Guix, 'guix system init' will
fail because it tries to build the broken 1.1.0-15.  Running 'guix pull'
inside the constrained installation environment is not a great solution,
particularly if substitutes are unavailable, so I created a new snapshot
in 6680880f9b8dceb4f2f3f91bd2b13c659b53835e.

(I had already encountered this today when reinstalling a machine.)
