Guix 1.0.0 was released recently. I have an old version that I installed once and did not use for a long time, so I decided to try 1.0.0.

$ guix --version guix (GNU Guix) 0.16.0 Copyright (C) 2018 the Guix authors License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law.

But it seems that I cannot upgrade it. I tried guix pull and also guix package -u guix , but then, when I run guix --version again, I get the same 0.16.0 version.

I also tried running the installation script again, but it finds the old version and refuses to overwrite.

(I'm using the Guix package manager on a Debian system)

What would be the proper way to upgrade?
