Hi Guix

Installation of the package `python-pastel` fails on my system.

```
$ guix pull

I guess it must be a problem on my side as all the packages go through
CI!?

Tanguy,

No and yes but.

All packages do ‘go through CI’: ci.guix.gnu.org builds each new 
package, and whenever that succeeds, everyone gets a nice 
substitute for it.

However: we don't use CI success as a condition for merging 
commits to master (a commit must already be on master for CI to 
even see it).  There's also no ‘stable’ branch that only gets 
commits that were successfully CI'd.  Committers or users aren't 
notified of CI failure in any way.

There is much room for improvement in this area.  However, *for 
me*, the false negative level is still too high to justify working 
on it.

Kind regards,

T G-R

Thanks for the explanations! This makes things clearer!

Does it mean that I have to submit a patch the usual way to fix it?
Should the subject be something like "[PATCH] gnu: Fix python-pastel"?
