Hello! I want to ask novice's question, cause the first I want, having trouble, is to re-install GuixSD, but rescue with USB-stick is faster.
I have for second time a bug described here: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=31162
Both times, as I think, it happened this way. I run `guix pull`, switch off notebook while it is running (just a mistake) and then I run again `guix pull`, it works, but gives the errors.
Here it is log I copied from terminal: https://pastebin.com/7c06ER7v
Guix is not working at all.

# guix gc -R $(readlink -f ~/.config/guix/latest)

I reported this bug to Bugs Maillist. But for future want to ask how can I rescue broken system booting with GuixSD USB-stick?

The mechanism used by “guix pull” has changed.  These errors no longer
happen with the new mechanism.

> # guix gc -R $(readlink -f ~/.config/guix/latest)

~/.config/guix/latest is no longer used.  Instead “guix pull” installs a
full self-contained Guix to ~/.config/guix/current/bin/.

If you don’t have this you are likely upgrading from an old version of
Guix before that change was made.  In that case you need to upgrade to a
version of Guix that has a guile-gcrypt package, then install it, and
only then run “guix pull”.

With the new mechanism you can simply use any of the older variants of
Guix you have in ~/.config/guix/current-n-link/bin.

Hope this helps!

Thank you, Ricardo Wurmus, for these exact instructions.

I have that bin directory:

# cd ~/.config/guix/current/bin/
~/.config/guix/current/bin# ls
guix  guix-daemon

And I have no upgrades for guix. As I thought before upgrading process is `guix pull && guix package -u ATOM`

# guix package -u guix
# guix --version

Did you mean Guix version  67ad5532f76b53e955149da2f1e237696ff0893 that provide gcrypt?
Can I run `guix pull` now?

Oh, you have “guix” installed with Guix…?  Could you please show me the
output of “which guix”?  You should be using
~/.config/guix/current/bin/guix — that directory should be first on
PATH, and you probably shouldn’t install the “guix” package itself,
because it will necessarily be older than the version of Guix you used
to install it.

# which guix
/root/.config/guix/current/bin/guix
# echo $PATH
/root/.config/guix/current/bin:/root/.guix-profile/bin:/root/.guix-profile/sbin:/root/.guix-profile/bin:/run/setuid-programs:/run/current-system/profile/bin:/run/current-system/profile/sbin

So, I can run `guix pull` ?
One more question. Often I have troubles that installed by root packages are not visible for root. I think this is because of PATH. So I have added this to /root/.bashrc , as these instructions appeared while I run `guix package -i ATOM` :

# tail -n 6 /root/.bashrc

# my
export PATH="/root/.guix-profile/bin${PATH:+:}$PATH"
export PATH="/root/.guix-profile/bin:/root/.guix-profile/sbin${PATH:+:}$PATH"
export PATH="/root/.config/guix/current/bin${PATH:+:}$PATH"

Is it right way? Does it work, when I run `su`?


PS. Hope my mail will not appear in Maillist archive.

Environment variable definitions should go to ~/.bash_profile rather
than ~/.bashrc (the former is for “login shells”, the latter isn’t).
Other than that it looks good.

> Does it work, when I run `su`?

‘su’ doesn’t source root’s ~/.bash_profile; you have to run ‘su -’ to do
that.

HTH,
Ludo’.
