Well, for me Emacs is not broken.  Your initial issue is about:

--8<---------------cut here---------------start------------->8---
libm17n-core.so.0: cannot open shared object file: No such file or directory
--8<---------------cut here---------------end--------------->8---

Now, is it solved for you?


Then this issue…

is another one.  And from my experience, it is about a conflict about
the channels.

IMHO, the issue comes from this.  As Maxim suggested [1], you should
run:

        Do you use channels?  If so, could you

        $ mv ~/.config/guix/channels.scm{,.bak}
        $ guix pull
        $ guix environment --ad-hoc emacs -- emacs --version

and it should fix the issue.  This…

…suggests you have a ~/.config/guix/channels.scm file and one of the
channel has a conflict with master.
