RE: guix pull fails while Migrating profile generations

[Henk Katerberg <henk.katerberg@verum.com>]

Hi Ludo,

root@stoeptegel ~/.config/guix# ls -al
total 8
drwxr-xr-x 2 root root 4096 Nov  6 08:55 ./
drwxr-xr-x 3 root root 4096 Oct 19 13:33 ../
lrwxrwxrwx 1 root root   33 Oct 25 09:16 current -> /root/.config/guix/current-1-link


I have since performed the following steps:
  cd /var/guix/profiles/per-user/root
  rm current-guix-1-link
  rm current-guix-2-link
  rm current-guix-3-link
  rm current-guix-4-link
  rm current-guix-5-link
  rm current-guix-6-link
  rm current-guix 
  /run/current-system/profile/bin/guix pull

That pull no longer complained and seems to have been successfull:

root@stoeptegel ~/.config/guix# ls -al
total 8
drwxr-xr-x 2 root root 4096 Nov  6 09:01 ./
drwxr-xr-x 3 root root 4096 Oct 19 13:33 ../
lrwxrwxrwx 1 root root   45 Nov  6 09:01 current -> /var/guix/profiles/per-user/root/current-guix

root@stoeptegel ~# ls -al /var/guix/profiles/per-user/root
total 8
drwxr-xr-x 2 root root 4096 Nov  6 10:57 ./
drwxrwxrwt 5 root root 4096 Nov  6 08:54 ../
lrwxrwxrwx 1 root root   19 Nov  6 09:59 current-guix -> current-guix-2-link
lrwxrwxrwx 1 root root   51 Nov  6 09:59 current-guix-2-link -> /gnu/store/17mlp6dhc65mpqrm2x0w7p45znqxcfhs-profile

The machine is currently performing a guix system reconfigure. So, I think I've recovered.

Unfortunately, I have no way of reproducing the erroneous situation. I have experienced the problem on two distinct GuixSD installations and got there throught normal guix commands (no manual tinkering).


Regards,
Henk

It seems that everything was migrated and is OK, but
~/.config/guix/current still points to the “old” target no?

Could you make sure you have something similar to this:

  $ readlink ~/.config/guix/current
  /var/guix/profiles/per-user/ludo/current-guix

?

HTH!

Ludo’.
