Therefore closing.

Hi all,

I am suddenly having errors with guix pull while pulling my own custom
channels, after upgrading guix yesterday. My custom channels has not
changed since early April. I am sure I was able to pull from my custom
channels when I last upgraded around early June.

The error is "channel dependency has an invalid introduction field," but
the introduction fields of my custom channels have the same form as those I
use for GNU guix and nonguix channels which I can pull without errors; and
the channel introductions and GPG fingerprints are unchanged from the last
time I was able to pull successfully (I have the channels.scm file under
version control).

There are two private channels. Including either of them are sufficient to
replicate the error; at least one is necessary to replicate the error.

Command line output:
