bug#27418: `guix pull` gets stuck at "updating substitutes from 'https://mirror.hydra.gnu.org'... 100.0%"

[Mekeor Melire]

Hello Guix!

Yesterday, I installed GuixSD on yet another device. (I did `guix pull`
before `guix system init ...`, so I guess I installed the latest version
from the master-branch of the Guix' Git-repository on the system.)

After rebooting, I ran `guix pull` (as root) but it didn't stop printing

    substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... 100.0%

even after letting it run over night for like 8 hours.

I asked for help on #guix@freenode and rekado confirmed my issue:

    <rekado_> mekeor: I see the same with master
    <rekado_> but a couple of commits back it seems fine

(And finally, assuming this bug gets fixed, I wonder if/how I will be
able to pull a working version of Guix if I only have one=this
non-functional version of Guix installed.)

Following rekado's friendly advice, I was able to downgrade guix with:

    guix pull --url=https://git.savannah.gnu.org/cgit/guix.git/snapshot/01049bb0c1f3f69afb8d1782f99ca5c0adaed946.tar.gz --no-substitutes

where both options (--url and --no-substitutes) were neccessary. Now,
everything seems to work again: commands like `guix package -i` and
`guix system reconfigure` no longer get stuck at "updating list of
substitutes".

Thanks, rekado.

Still, I wonder
  * what caused this issue;
  * if anybody else is/was experiencing it; and
  * when it will be fixed in master-branch (i.e. when I will be able to
    `guix pull` and `guix pull` again successfully).

I’m not sure but it may have been caused by a hung “guix publish”
process.  This could have given you bad substitutes, which have been
added to your cache at “/var/guix/substitute/cache/”

>   * if anybody else is/was experiencing it; and

Others have reported it but I couldn’t reproduce it on my main machine.
This makes me think that it may have been a temporary issue with effects
on the local cache.

You may need to delete your substitute cache under
“/var/guix/substitute/cache/”.  jsierles on IRC reported that this fixed
their issue.

Could you please try that and report back?

Indeed, yesterday I realized ‘guix publish’ on hydra.gnu.org was stuck
for unknown reasons, meaning that it would not reply to HTTP requests
nor would it “bake” archives.  That’s likely the root cause.

Sorry about that!

Yes, this issue no longer appears for me. Thank y'all. Could you close
the bug?

I’m closing this by sending email to 27418-done@debbugs.gnu.org.
Thanks!
