Guix Halts After "updating substitutes from …"

Guix Halts After "updating substitutes from …"

[Wamm K. D.]

Hey, hey; 'not sure what caused this but my ~guix~ command suddenly
started getting stuck, when I do a pull or try to install a package,
after

> substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%

I haven't let it run for longer than an hour but it just sits there and
doesn't progress any further. When I run ~guix upgrade~, it halts,
similarly, after listing which programs it's going to upgrade.

Anyone, possibly, know what this is (or, at least, how I might get
around it)?

Thanks for any help!

Sure: 
<https://lists.gnu.org/archive/html/guix-devel/2022-05/msg00243.html>

Use ‘--substitute-urls=https://ci.guix.gnu.org’ (i.e., remove 
bordeaux from the default list) until it's resolved.

Kind regards,

For some quick diagnostics maybe you could try running it with strace,
or attaching strace to the running process to see if it's stuck on a
system call or if it's some kind of deadlock or livelock or other
concurrency related fun.
Actually... I thiiink I've experienced a hang like this on my i686
machine, but aborting it and running pull again fixed it.
Does it happen always?

Huzzah! That did it. Thanks so much, Tobias.

Thankfully, no; Tobias had the scoop:
https://lists.gnu.org/archive/html/guix-devel/2022-05/msg00243.html.

Removing the =bordeaux= substitute server made things run as
expected. Gonna just keep doing that until things're resolved.

Thanks for a ton for reaching out with some help; /very/ much appreciated.

Thank you! 

I've been having the same problem and had no idea what caused it.

Wouldn't adding a timeout make sense? Either with a sensible default time and options to change or disable it or just configuration options that would be documented in the "channels" section?

If timeouts aren't an option, a message like "could not reach substitute server [server-name] ([time/unit])"* would already be much more be helpful than the current state for those of us who are not (yet) that familiar with guix.   

I regularly feel like guix errors could give more useful information. Is this due to design decisions or something that just hasn't been considered or worked on?


* Optionally with additional information like "Press 'Control C' to abort" and "You can temporarily disable this substitute server by adding  '--substitute-urls=[server-name] to the command that got you here.'"
