Re: Repair / reinstall Guix package manager (foreign distro)

[Zelphir Kaltstahl <zelphirkaltstahl@posteo.de>]

Hi!

Thank you both for your responses!

In the end I had already begun removing everything that

find / -iname '*guix*

would give me and that was not created by me, so I went the route of
reinstallation.

However, I'll archive these e-mails and in case I ever forget the `-i`
in the sudo command again, I have the solution ready : )

Btw.: I deleted a whole lot more files than I thought I would need to. I
make a list and only after the last 2 removals, the Guix installer would
not find a previous installation any longer:

~~~~
   rm --recursive --force /gnu/store || true;
   rm --recursive --force /var/guix || true;
   rm --recursive --force ~/.guix-profile || true;
   rm --recursive --force ~/.config/guix || true;
   rm --recursive --force /etc/guix/profile/config.scm || true;
   rm --recursive --force /tmp/guix.* || true;
   rm --recursive --force /home/xiaolong/.cache/guix || true;
   rm --recursive --force /root/.cache/guix/ || true;
   rm --recursive --force /root/.cache/guile/ || true;
   rm --recursive --force /var/log/guix || true;
   rm --recursive --force /root/.config/guix || true;
   rm --recursive --force /etc/systemd/system/guix-daemon.service || true;
   rm --recursive --force /etc/guix || true;
   rm --recursive --force /usr/local/bin/guix || true;
   rm --recursive --force /etc/systemd/system/multi-user.target.wants/guix-daemon.service || true;
   rm --recursive --force /usr/local/share/info/guix.* || true;
   rm --recursive --force /tmp/guix.Mgm || true;
   # all of the above does not help
   # you need to do also the following
   rm --recursive --force /var/guix || true;
   rm --recursive --force /gnu || true;
~~~~

Thanks for telling me about the need to use `-i` or `su -`, I did not
know about it. I would have run into this problem again and again.

Regards,
Zelphir
