Also, using a year old guix client gives the same error. It is in the
daemon.

And running an older daemon fixed it:

There must be a typo in the code somewhere. The path should be
'/root/.config/guix/current/bin/guix'.Note the extra 'guix' path
component.

Good catch!  Fixed in 799dc53e9bfe605613cd2e7cb2c584282847fa84.

Not completely sorted. Not sure what is going wrong but now starting
with guix 0.14 daemon and client and running guix pull a few times
successfully, running guix-daemon from $HOME/.config/guix/current/bin
and guix from a fresh git checkout using ./pre-inst-env guix I get

substitute: /gnu/store/x02v3j0h5q1d9bl3lwxavp8m9rpm3b7m-guix-daemon-0.15.0-2.8bbb79c/libexec/guix/substitute: line 8: /root/.config/guix/current/bin/guix: No such file or directory

which is funny for two reasons - 1st this is a guix-daemon that
appears to be older (it is the same) referring to a directory that
does not exist - guix pull is in my $HOME/.config.

Note that it still downloads binaries, but won't do the final
symlinks in the profile.

On this machine I am stuck because whatever I do I get this error.
Only rolling back to 0.14 allows me to install software again
including guix. But then it stops in its tracks with above.

Since ‘guix-daemon’ runs as root, the ‘guix-daemon’ package¹ assumes
that ~root/.config/guix/current/bin/guix exists.  In fact, the only way
you can install the ‘guix-daemon’ package is by running ‘guix pull’, and
if you run ‘guix-daemon’ you run it as root, so ~root/.config/guix
necessarily exists.

Or could it be that you’re running ‘guix-daemon’ from
~/.config/guix/current as non-root?  That would indeed fail.

In fact it may be enough to do:

  exec ~/.config/guix/current/bin/guix …

instead of:

  exec ~root/.config/guix/current/bin/guix …

in that ‘install’ phase of ‘guix-daemon’.

Thanks,
Ludo’.

I still face this problem on one or two machines. I am running a
standard setup. Not sure what it is.

But since no one else is reporting I think it must be because I am
running some earlier tree checkout too for deployment. Something got
messed up.

You can close this issue for now. I'll simply reinstall Guix on these
machines and start building a recent tree.

  (resulting build failure etc., nothing interesting)

This is on recent source code checkout (commit
fefe17b0888b467383ea91fed73a9586295c49f0) with a small modification
(update of hdf5 to 1.10.3).

My guix-daemon is started via systemd at boot time, so it should run as
root. It's from root's guix, which is about two weeks old and has not
caused any trouble before.

Just to report that I did a successful install on one of those

  guix pull

restarted daemon using the new one in /root/.config/current/bin/

switched to normal user using the guix pointed in that directory

  /gnu/store/47hhyj0l4nk4na09qx1b66sz1wvpx95i-guix-command pull

Dear Ludo,

If I understand 'guix pull' correctly below should simply not be
possible, right? I mean, once you do a guix pull you have the latest
and the greatest and there should be no interference? Intriguingly
this does not happen on all my systems, just on 2 - notably my laptop
I am using in Southern France ;)

Pj.

It is working now. After a guix pull I did a guix package -i guix in a
new profile. Restarting the daemon from there it stopped complaining!

I don't know why the deamon from guix pull straight was not working,
but at least guix is building again.

I don’t think you’re doing anything wrong.  Could anyone of you who
experience this problem strace guix-daemon?  I’ve thought about this and
don’t understand where that EACCES (“Permission denied”) comes from.

Specifically, you’d have to run something along these lines as root:

  strace -f -p $(pidof guix-daemon) -o log

and then, as root or non-root (it doesn’t matter), run, say:

  guix build curl -S --no-substitutes

Thanks in advance!

Ludo’.

The log file (compressed) is attached.

In doing this I noticed that I have two guix-daemon processes running:

root      1583  0.0  0.0  33156  2412 ?        Ss   08:55   0:00 /root/.config/guix/current/bin/guix-daemon --build-users-group=guixbuild
root     13003  0.0  0.0  36028  6256 ?        Ss   11:28   0:00 /root/.config/guix/current/bin/guix-daemon 12770

I ran strace on the first one.

Konrad.

The download process is running as a build user, not as root, hence the
permission issue (silly me!).

Now we need to find a way to use ‘guix’ from root’s
~/.config/guix/current.  A solution may be to expose that profile under
/var/guix/profiles.  Needs more thought…

Thanks for helping out!

Great! Any quick hacks to fix this? Even when I set all permissions open I get in the latest tree

Hmmm. It fixed itself when I added the mirror substitute URL again.
After that it successfully built ghostscript. Looks like the building
problem only exists in the pre-building track of guix where it builds
packages for its own use?

A quick workaround is to run ‘guix-daemon’ from the ‘guix’ package.  So,
as root, you’d do:

  guix pull             # if you haven’t done it recently
  guix package -i guix  # to install or upgrade guix

Then make sure your systemd (or whatever) config file returns to
/var/guix/profiles/per-user/root/guix-profile/bin/guix-daemon as it
does when you install Guix from the binary tarball.

HTH!

The issue affects downloads only (fixed-output derivations, not

Hi there!

I believe commit ed9d7cb4d95f8f4776e6fee2778ab52bc2852969 fixes it.

That is, if you run ‘guix pull’ as root and then start
~/.config/guix/current/bin/guix-daemon, everything should be fine.

Thanks,
Ludo’.

Let's say the bug seems to be elsewhere now ;-)

When I try to build something after following your instructions, I get 
the error message

/gnu/store/bkkf11ixn67cwcw05nw9w9yd68i4jf23-guix-daemon-0.15.0-5.1d0be47/libexec/guix/download: 
line 8: /var/guix/profiles/per-user/root/current-guix/bin/guix: No such 
file or directory

And indeed there is no guix at that place. I guess it should be

/var/guix/profiles/per-user/root/guix-profile/bin/guix

I can try fixing the download script and testing again, but not before 
next week, sorry!

Konrad.

Hmm you might need to run, say, ‘guix pull -l’, to make this script
magically appear.  :-)

Concretely, the new ‘guix pull’ migrates things from ~/.config/guix to
/var/guix/profiles the first time you run it, but it may be that you
haven’t yet run the *new* ‘guix pull’.

HTH,

It works on one problematic machine. Thanks!

That looks like the right direction, since running "guix pull -l" starts 
by saying

   Migrating profile generations to '/var/guix/profiles/per-user/root'...

Unfortunately, its next statement is just as magic but less pleasant:

Backtrace:
           6 (primitive-load "/root/.config/guix/current/bin/guix")

"/var/guix/profiles/per-user/root/current-guix"] 338b460>


This looks like an error in an error-raising procedure, something like  
a meta-error ;-)

Looking at

  ~# ls -l /var/guix/profiles/per-user/root/current-guix
   lrwxrwxrwx 1 root root 14 oct.  15 13:51 
/var/guix/profiles/per-user/root/current-guix -> current-4-link

yields  a link that is indeed missing. What I do have is 
current-guix-4-link, but not a plain current-4-link.

Yes, it’s one of the thinkos I made, fixed in
aa227b3be3d7728331a08dbd139c47c9b271dc23.

If you’re familiar with Dired in Emacs, I’d suggest opening
/var/guix/profiles/per-user/root and fixing the symlink targets from
there (with C-c C-q).

If not I can try and come up with a script to do that.

Apologies for the mess!

Done. And after rebooting, guix seems to work fine for root, including
the download phase. Meaning that I consider this bug fixed.

But there still seems to be some collateral damage, since I could not
use "guix pull" any more on my standard user account:

  $ guix pull
  Migrating profile generations to '/var/guix/profiles/per-user/hinsen'...
  guix pull: error: rename-file: Invalid cross-device link

This looks like guix is trying to use a hard link instead of a symbolic
link somewhere. I found a way around which I describe here for the
benefit of others who might find themselves in the same situation:

 - check out a local copy of the Guix repository 
 - configure and make as described in the manual
 - ./pre-inst-env guix pull

That does the profile migration using the very latest code. After that
the standard guix command seems to work fine again.

Konrad.

This was fixed in a subsequent commit:

  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=8036b0942b89022147aaf9cd9940988fdbcc19ef

To work around it, you can pull from an older generation, along these
lines:

  ~/.config/guix/current-42-link/bin/guix pull

(This will work because this older guix won’t attempt to move your
generations to /var/guix/profiles, so it allows you to “jump over” the
bug.)

Let me know how it goes!

It’s terrible that a function like this that looks trivial has been
causing so much trouble.  Sorry about that.  :-/

I cannot try any more because I already used another workaround, meaning
that my profiles are properly migrated.

Lesson learned: avoid messing around with mutable state. How about
creating a functional package manager?  ;-)

LOL

This whole update to guix pull was somewhat a breaking change, but 
unfortunately it was very hard to imagine the repercussions (horrible 
bugs) down the line...

Could it have been completely avoided by introducing it as such and 
forced people to reinstall/upgrade by reinstall (overwriting all files 
and invalidating the store etc.)?

Fundamentally, it’s just about moving files from ~/.config/guix to
/var/guix/profiles/per-user/$USER, which I thought was fairly harmless.

Also, the bug was around for a few days.  Those who were away during
those days didn’t notice.

That said, I agree this was poorly handled.  One way to improve it would
be to have several people run the code on their machine before it goes
to master (it’s the kind of code for which we can hardly write unit
tests, and it’s single-use code.)

Thanks,
Ludo’.
