Guile doesn't like carriage returns after \

guix pull fails for a 4 days at least with the same error:

fish:

"/home/shegeley/.cache/.fr-sqOEpp/273vsd5gv1ch73ayih504s5wcxvysq-module-import-compiled.drv"

I had nix-service-type enabled and I had this problem. Then I disabled it

(with remove-service...), reconfigured the system. Same error message and

problem. Cleaned the thrash (guix gc) and tried to pull without

substitutes. Same result each time.

That's an error message from fish, not from guix.

Why is fish trying to run nix on Guix System?

Maybe you configured fish to interpret output lines containing ".drv"?

Hm...

I just use the "default" fish as home-service and it's set as my user's

shell... I will try to change them both to bash and try again. Maybe that's

a "non standard-shell" issue.

Ok. Now it's /gnu/store/87kif0bpf0anwbsaw0jvg8fyciw4sz67-bash-5.0.16/bin/bash:

I have no idea what's going on here. Guess there are some

nix-interpopability that fails somewhere.

Also: noticed that all associated nix-directories (~/nix-profile, ...)

exist, have root chown, and are not empty. There is even a spotify that I

installed with nix earlier, in ~/.nix-profile/bin. Although I removed nix

from services and packages in my system-wide config.

This is very weird, because:

1. what's a derivation doing in $HOME?

2. This would mean that, while compiling some guile modules, fish is

invoked and fish is calling nix. But nix and fish are not involved at

all when compiling guile modules. (The only mention of 'fish' in the

source code is in shell completions.)

3. How did $HOME get leaked to the builder?

4. How did 'show-derivation' appear in the builder? There's no mention

of 'show-derivation' anywhere in guix' source code.

Maxime.

Sorry. Forgot to mention the thread.

Although I was able to "guix pull" with "sudo", as root user normally. As

Can I use the result from root somehow?

I tried different approaches to copy guix-related stuff from root to my

user and failed each time. I mean: I've failed each time with almost the

same error as at the beginning except for the log was about escape sequence

from the very beginning.

After the last letter my laptop's motherboard broke. It was replaced

recently but all the data was lost from the SSD due to encryption...

TLDR: I made a backup and reinstalled the system.

But the problem still persists. How can I safely move root's profile into

the user's one? Tinkering with any root-related things is a danger zone

for me, so I won't do anything on my own until there are any clear

instructions.

As previously: from root "guix pull" works perfectly. From users it has the

same problem (nix-related error).

Hi,

Grigory Shepelev schreef op ma 27-12-2021 om 17:27 [+0300]:

You could try deleting /var/guix/profiles/per-user/$USER and running

"$THE_GUIX_OF_ROOT pull" and "$guix install ...". I don't see why that

wouldn't work, but I've never tried it and 0 warranty.

Could you search for "show-derivation" in the back-up? E.g. with grep -

rF show-derivation. Maybe there's a leftover from when you used nix

somewhere ...

Greetings,

Maxime.

Created new user. Tested from it. Guix pull works great. Now will move the

stuff.

Thanks a lot.

Seems like the issue has been resolved, so closing.

If you want to re-open the bug report, see

https://debbugs.gnu.org/server-control.html.

Greetings,

Maxime.

Encountered same problem again on both machines (recently installed guix on

laptop and an old desktop PC of mine).

Seems like the problems arise after home reconfiguration. Still can pull

successfully from the root user.

On "usual user" I have to move all my stuff from home to a separate

directory.

cd ~; mkdir vault; mv * vault; mv .* vault;

Then guix pull works. Of course all the home configuration content is lost.

And I have to reconfigure my home. And then recover all files except for

".guix-home" and etc. from the "vault" dir.

I wondered that happens because of wrong lang/locale settings, So I even

forced them in my user's config:

(simple-service 'some-useful-env-vars-service

home-environment-variables-service-type

`(("LC_ALL" . "en_US.UTF-8")

("LANG" . "en_US.UTF-8")

("GDM_LANG" . "en_US.UTF-8")

("LANGUAGE" . "en_US")

("EDITOR" . "emacs")))

Still the same problem.

See https://debbugs.gnu.org/server-control.html for how to re-open.

What is the ‘same problem’ here? IIRC, there were two separate

problems.

Do you mean this one:

Unknown command: nix fish: nix show-derivation "~/.fr-sqOEpp/....

module-import-compiled.drv"

I didn't know you were using "guix home", was this also the case in the

original report? This seems potentially relevant information. The

exact contents of the home configuration (with personal information

removed and preferably reduced to a minimal test case) could be useful

to investigate the issue.

Or was ‘same problem’ the following
