[Message part 1 (text/plain, inline)]

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:

The branch ’keyring’ seems empty, is it expected?  I mean the manual
reads:

        Additionally, your channel must provide all the OpenPGP keys
        that were ever mentioned in .guix-authorizations, stored as .key
        files, which can be either binary or “ASCII-armored”. By
        default, those .key files are searched for in the branch named
        keyring but you can specify a different branch name in
        .guix-channel like so:

Hi Simon,

Thanks for taking a look! The keyring branch doesn't seem empty on my end,
though. https://github.com/ning-y/ninguix/tree/keyring

Maybe it looks empty because it is an orphan branch? I always had it as an
orphan branch though (that part never changed) and it had worked before.

I was able to pull my custom channels without error after pinning the GNU
Guix repository (https://git.savannah.gnu.org/git/guix.git) to commit
f2e98587 (21 May). The Guix CLI version for this commit was version
d884fc9e2efecfba09af4694f5a13ad7fc6f704f.

(channel
        (name 'guix)
        (url "https://git.savannah.gnu.org/git/guix.git")
        ; (branch "master")
        (commit "f2e98587ec72b5f5c2ec79956ced129350396bab")
        (introduction

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.

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

Therefore closing.

Feel free to reopen if I have misunderstood.
