bug#50941: Potential bug in guix home

Hi!
 I assumed user privileges should be enough for guix home, but guix home reconfigure home.scm returns this result:

/gnu/store/…-home
guix home: error: mkdir: permission denied


This happens in a fresh and up to date VirtualBox VM with the only changes being a few installed packages (emacs, vim & tmux) and the guix home configuration.

Please tell me if I forgot any relevant piece of information.


Best regards,

Pascal

It’s hard to know why this happens without some more information.

Could you share a bracktrace if there was one, and what’s the contents
of the ‘home.scm’ file?

Does the issue happen if you run ‘guix home build home.scm’?

I guess I reproduced this.  No, guix home build has no errors.

reconfigure requires /run/user directory which doesn't produced by
%base-services, but %desktop-services with [1] probably does.

[1] (service-extension file-system-service-type (const %elogind-file-systems))

bug#50941: I can confirm this bug too

[jgart via Bug reports for GNU Guix]

I was going to report this today but Pascal beat me to it.

I get the same error when running `guix home reconfigure file.scm`.

`guix home build file.scm` builds fine without errors.

Here's the config that I tested that with:

```
(use-modules (gnu home)
             (gnu packages) 
             ;(guixrus packages guix-easy) 
             (gnu packages bash)
             (gnu packages mail)
             (gnu packages messaging)
             (gnu packages password-utils)
             (gnu packages guile)
             (guixrus packages bower)
             (gnu packages guile-xyz)
             (gnu packages wget)
             (gnu packages version-control)
             (guixrus packages bower)
             (gnu packages emacs))

;;(define* (pkgs #:rest lst)
;;  (map specification->package+output lst))

(define-macro (define-tools group-name . group-package-names)
  "custom helper for defining groups of packages"
  `(define ,group-name
     (map (compose list specification->package+output)
          ',group-package-names)))

(define-tools jgart-profile "emacs-minimal" "offlineimap3" 
   "guile-pipe" "bower" "guile-colorized" "guile-readline" "tig"
   "git" "gajim" "gajim-omemo" "keepassxc" "wgetpaste")

(define jgart-packages
  (home-environment 
   (packages (list tig wgetpaste))))

jgart-packages
```

I'm forgot to mention that I tested this on void linux.

Sorry for the unused code in the example.

Ah, then this would be the same problem as bug#50945.

Can you try setting XDG_RUNTIME_DIR to someplace that you have writable
and then running reconfigure again? I have to warn you though I don't
have a good answer for what to do if it works this time and doesn't work
if you log out and log back in again.

bug#50941: XDG_RUNTIME_DIR

That did not change a thing for me:

$ mkdir ~/tmp
$ XDG_RUNTIME_DIR=~/tmp/
$ guix home reconfigure ~/home.scm
/gnu/store/dhd3pgpzjzynfyd42kgldh18j40q8zda-home
guix home: error: mkdir: Permission denied

I don't know if that matters, but XDG_RUNTIME_DIR was not set at all before (only XDG_CONFIG_DIRS and XDG_DATA_DIRS.)

XDG_RUNTIME_DIR might need to be exported as an environment variable:
$ export XDG_RUNTIME_DIR=$HOME/tmp

That fixed it for me.

Specifically `export XDG_RUNTIME_DIR=$HOME/tmp` like Maxime mentioned.

I think this should be documented for guix home users on a foreign distro so they
don't get frustrated with this detail of getting set up.

WDYT?

Or is there another way that this configuration should be managed on a foreign distro?

all best,
