bug#65101: Singularity can't find basic programs

[N. Y.]

On guix (GNU Guix) 5aceacac65784bd2e1fd12304f965ae6026de49d, trying to
build a Singularity image, I get many "command not found" errors for the
programs id, install, zcat, and tar:

In my system.scm, I have both the singularity package:

  ;; Packages installed system-wide.  Users can also install packages
  ;; under their own account: use 'guix search KEYWORD' to search
  ;; for packages and 'guix install PACKAGE' to install a package.
  (packages (append (map specification->package '("nss-certs" "ntfs-3g"
"singularity"))
%base-packages))

As well as the service:

  ;; Below is the list of system services.  To search for available
  ;; services, run 'guix system search KEYWORD' in a terminal.
  (services
   (append (list (service gnome-desktop-service-type)
 (service cups-service-type
   ; http://localhost:631
   (cups-configuration (web-interface? #t)))
 (service bluetooth-service-type)
 (set-xorg-configuration
  (xorg-configuration (keyboard-layout keyboard-layout)))
 (service docker-service-type)
 (service singularity-service-type))
   ;; This is the default list of services we
   ;; are appending to.
   %desktop-services))

p.s. I also cannot build images without sudo, but I do not know if this is
intended:

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 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.

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.

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

[N. Y.]

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:
