bug#64006: Installation frustration weekend

[pelzflorian (Florian Pelz)]

Hi Denys!  Sorry to hear, but thank you for writing which bugs still
cause trouble with Guix System.

I can say this:

Not being a maintainer, I have not looked at the dump, but as you
reported, apparently this will be fixed by making a new Guix release,
because the latest Guix has fixes for dealing with substitute server
errors.

You can use “guix install netcat” in the installer, probably, at least
it will work after running “herd start cow-store /mnt” as described for
manual installation in the manual.  Not a bug in my opinion.

Yes … this is a bug, but how to fix it; does Debian do better?

This sounds like a bug/regression; in the source code
<https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/services/base.scm>,
it looks like it should work, because it uses GNU Unifont, but it does
not display Cyrillic for me either.  However, you could add kmscon to
your operating system config’s services field to make console fonts work
for all languages, for example like this

(services
 (cons* (service kmscon-service-type)
        …
        %desktop-services))

Yes, I think double downloads cannot be fixed, because the installer is
tested to provide a first working version (except download errors …),
but it will always be outdated.

But why there are duplicate substitute messages in the console, I do not
know.  Is it a bug?

Both have the same effect for me.  Shift+Alt and Alt+Shift both work for
me.  Strange.  What happens when you change the combination in your
operating system config’s keyboard layout settings and reconfigure?

Did it work in Debian?  Did you use nonfree drivers before?
