Dear Maintainer,

i have installed package guix (1.2.0-4).
and try to run guix pull:

[code]

[/code]

i was able to work around this error:
[code]
$ guix pull --branch=version-1.3.0
[/code]

but even after that I couldn't get updates from master:
[code]
$ guix pull
Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'...
guix pull: error: aborting update of channel 'guix' to commit a9abb75dc87c0fe532905746912a39250d97293f, which is not a descendant of aa34d4d28dfe25ba47d5800d05000fb7221788c0
hint: This could indicate that the channel has been tampered with and is trying to force a roll-back,
preventing you from getting the latest updates.  If you think this is not the case, explicitly
allow non-forward updates.
[/code]

and this command generates exactly the same error as described at the beginning:
$ guix pull --allow-downgrades

as far as i understand, in order for "guix pull" to work,
it is necessary to update the guix and guile* packages.

...

try with the commit from v1.3.0 (ideally from a fresh install, or maybe
using --allow-downgrades):

  guix pull --commit=a0178d34f582b50e9bdbb0403943129ae5b560ff

and then:

  guix pull

Though it might get you roughly the same issues.

Massive changes were recently merged into guix master, so it wouldn't be
terribly surprising if something incompatible crept in...

I'll try to reproduce the issue, though not sure exactly when I'll get
the chance.

I don't have a stackexchange account or I'd comment there...

The step where you "guix install guix" will always install an older
version of guix than you have through guix pull; that should not be
needed. What were you trying to solve with that step?

Maybe run "guix remove guix" to get back to the version from "guix pull"
and log out and log in again, and see if that helps...

Is ~/.config/guix/current/bin in your $PATH? If you log out and log back
in again, /etc/profile.d/guix.sh should add the right variables to your
path. If $PATH does not contain ~/.config/guix/current/bin, as that is
where "guix pull" installs guix.
