Subject: A channel is impossible to remove if it becomes inaccessible
Date: Sat, 28 Sep 2024 18:31:26 -0500

A channel is inaccessible, so I have disabled it in my home config:

        (simple-service 'channels-service
               home-channels-service-type
;;                (list
;;                 (channel
;;                  (name 'gooby-channel)
;;                  (url
"https://gentooserver.dehnel.info/gitea/nathan/gooby-channel.git"))

I try to reconfigure the system to get rid of the channel so I can
guix pull. The reconfigure tries to fetch the channel which fails
because the server is down, which prevents me from removing the
channel or updating my system

Sorry for replying this late.  I believe you can work around this by
running ‘guix pull -q’ (ignoring ‘channels.scm’ files) or by explicitly
passing the list of channels that you need with ‘guix pull -C
channels.scm’.

Thanks,
Ludo’.
