Hi there!

Done!  :-)

Done, but it’d be nice to add more test of the installer!

Not much progress on these fronts.

We should really do that!

You can view them here:

  https://issues.guix.gnu.org/search?query=is%3Aserious+is%3Aopen
  https://issues.guix.gnu.org/search?query=is%3Aimportant+is%3Aopen

There’s quite some bug triage to be done, in fact (some are probably
already fixed.)  Let’s synchronize on IRC!

Now we can do:

--8<---------------cut here---------------start------------->8---
ludo@ribbon ~/src/guix$ ./pre-inst-env guix weather -m etc/release-manifest.scm
guix weather: warning: ambiguous package specification `guile@2.2'

This one is telling us that we have substitutes for 78% of the
“release-critical” packages, for all architectures.

There are build failures to look at (e.g., vim on armhf-linux).  You can
run ‘guix weather’ with ‘--display-missing’ to view the list of failing
items, and then you can try building them with, say:

  guix build $(guix gc --derivers /gnu/store/…-thing-that-fails)

Help welcome!

Then, system tests:

This suggests that there are (presumably) a bunch of system tests
failing.  Again, we can pass ‘--display-missing’ to see which ones.
I fixed a few tests recently.

If you’re confined at home anyway, that gives you plenty of ways to help
out!  :-)

How ’bout targeting a release next week?
