bug#64059: Sudden unexplained error during guix pull: "channel dependency has an invalid introduction field"

[N. Y.]

Hi Josselin,

Thank you so much for your help! Indeed, the .channels.scm files of my custom channels had invalid introduction fields. That's on me --- I should've read the error message more carefully!

Best regards,

Ning

I've purposefully added this new error to warn users that their
.guix-channel's introduction forms were erroneous.  Previously, they
were silently being dropped.  The formats in a channels.scm file and in
the .guix-channel file are *not* the same!  Please see "(guix) Declaring
Channel Dependencies" for an example of the format.

Best,
