How to remove guix

How to remove guix

[Mick Sulley]

I am having real problems with Unison, I installed via Guix and it is 
not working so I want to remove it and try with an apt install.

I have run

     guix package -r unison

and it seems to work, I have also installed unison with

     sudo apt install unison

and that seemed to work as well but then I see

mick@holly:~$ unison -version
-bash: /home/mick/.guix-profile/bin/unison: No such file or directory
mick@holly:~$

so it is looking for the guix version and not seeing the standard apt 
install.  So

1) How can I get it to look for the standard version rather than the 
guix version

2) How can I remove guix completely?  I have searched on-line and cannot 
see anything on this.

My PATH is

mick@holly:~$ echo $PATH
/home/mick/.guix-profile/bin:/home/mick/.config/guix/current/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
mick@holly:~$

Thanks

Mick

I think your issue is that bash keeps a cache of binary locations. You can try in a new terminal, or after running "hash unison" (no output if all goes well). Then you should be able to run the unison from apt.

You should remove /gnu, /var/guix, ~/.guix-profile and ~/.config/guix. Possibly some symlinks from /usr/local too.

Mick,

There isn't a more or less standard version, just bash caching the 
last used binary.  Use ‘hash -r’ to clear bash's cache and make it 
look again.

> My PATH is

(So $PATH isn't used at all once you've run unison in the same 
shell.)

Off the top of my head: remove

  ~/.config/guix
  ~/.cache/guix
  ~/.guix-profile
  /gnu
  /var/guix
  /var/log/guix

Also take a look at the installer script[0] to see what it creates 
and what you can remove.

Good luck,

Hi,

To remove Guix completely:

>   ~/.config/guix
>   ~/.cache/guix
>   ~/.guix-profile
>   /gnu
>   /var/guix
>   /var/log/guix

/etc/init/guix-daemon.conf
/etc/systemd/system/guix-daemon.service
/etc/systemd/system-store.mount
/etc/init.d/guix-daemon
/usr/local/bin/guix
/usr/local/share/info/guix*
/etc/profile.d/guix.sh

Remove the guixbuilder${i} user and th guixbuild group too.  Maybe
some bits more depending which guix-install.sh you used to install
Guix.

Hope that helps,

Hello Mick,

I once messed up my Guix installation, by not using sudo -i when trying
to update the root profile, so I had to go through removing it as well.
I wrote down all the things I removed though:

https://notabug.org/ZelphirKaltstahl/guix-package-manager-tutorials/raw/master/uninstall.org:

~~~~
   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 /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;
~~~~

This does not include the users or groups. Perhaps I did not uninstall
those, because I wanted to install it again afterwards.

Also (!) check all location first, to be sure you are not deleting
anything you still need.

Also: If any of this is not correct or damaging, please people correct
me : )

Regards,
Zelphir

Hi!

Thanks for sharing, this is very helpful.

Shouldn't Guix include an uninstaller then?  Looks like it would be
handy :)

I can't find any instructions in the manual either.  Am I missing
something or should we update the manual?
Providing an uninstaller would hit two birds with one stone ;)

There is a patch from Wed, 15 Jul 2020 waiting review about an
uninstaller script:
