No… 


I say so because the first step in the manual for "Copying to a 
USB
Stick" and "Burning on a DVD" says, "Decompress the image using 
the

xz command: xz -d guix-system-install-1.0.1.system.iso.xz".


Exactly: ‘decompress the image’, not ‘decompress the image and 
extract all its files’, as was being done in the screenshot. 
That's a pretty big difference!


Hence why it's best to follow the commands given in the manual: 
even if one doesn't know the difference between ‘decompressing’ 
and ‘extracting’ above, the command will do the right thing for 
you.

Buenas, Jorge:

Como dice Laura, hay un problema de permisos al intentar descomprimir el 
archivo usando Nautilus (conocido ahora como GNOME Files). A mí me ocurre igual 
(no sé si esto es un error). Sin embargo, si se descomprime siguiendo las 
instrucciones del manual, la descompresión ocurre sin problemas. Es decir, 
podés ejecutar las siguientes órdenes en un terminal para descomprimir el 
archivo ".xz":

$ cd ~/Descargas
$ xz -d guix-system-install-1.0.1.i686-linux.iso.xz

Estas instrucciones, junto con las demás instrucciones recomendadas para 
instalar y configurar el sistema, están en el manual:

https://www.gnu.org/software/guix/manual/en/html_node/System-Installation.html

Yo recomendaría seguir el manual al pie de la letra, como dice Tobias, para 
evitar resultados raros. Así también, si en cualquier momento se te presenta 
otro problema, nos podés escribir especificando el paso concreto que estás 
siguiendo en el manual, de manera que todos podamos estar en la misma página.

Suerte con la instalación :)

List available versions of package.

[Philippe Veber]

Hi all,

I'm getting started with guix, and so far it's been just fine. I would like
to see all available versions for a given package. Is there a command that
would help me with that?

Cheers,
  Philippe.

Welcome!


I would like to see all available versions for a given package.

There is:

 $ guix package --list-available=^glibc$
 glibc	2.25	out,debug,static 
 gnu/packages/base.scm:921:2
 glibc	2.22	out,debug,static 
 gnu/packages/base.scm:980:2

 …

For easier interactive use, you can use the short option ‘-A’.

Note that this option takes a regular expression as argument. 
That makes it powerful, but means you'll have to enclose the name 
in ‘^…$’ if you want to match one specific package.


Kind regards,

No…

Anyway, I think ‘follow the manual’ is the correct general 
solution to the problem (and many like it), and that message seems 
to have come across loud and clear.


Good luck, Jorge!

Problem with building service from my channel

[Jack Hill]

Hi Guix,

I have defined the planisphere-report-service-type in my channel 



This has been working well for me, and I have most recently been able to 
build my channel with `guix pull` with the following version of guix:


```
$ guix describe
Generation 5Jun 10 2019 13:44:44(current)
  guix 31775e4
repository URL: https://git.savannah.gnu.org/git/guix.git

  guix-at-duke 363d627

branch: master
commit: 363d6270d5e3505c34aa0dbfa221f64421497587
```

However, when I try to pull the most recent guix, 
aec9bb8793ca75a5bbc1731460ed4eb388764202, the build of my channel fails:


```

View build log at 
'/var/log/guix/drvs/hy/cfgn8iiy9z205zi1174sgcgs0vnm5r-guix-at-duke.drv.bz2'.
```

The build log is;

```
(repl-version 0 0)
(exception misc-error (value #f) (value "Unbound variable: ~s") (value 
(mcron-service-type)) (value #f))
```

Presumably there was some change to the mcron-service-type recently that 
requires changes in my channel, but I don't see what they could be or how 
to fix my channel.


What's going on here? What is the Guile exception trying to tell me?

Best,
Jack

Grafts are are ignored in some parts of Guix.  In this case, if you
inspect the profile derivation when doing 'guix install -n
ungoogled-chromium', you can see that the computed profile.drv needs to
produce the ungrafted ungoogled-chromium-x.y.z.drv, because the
profile-builder references the _ungrafted_ package. 

I'm not sure of the exact mechanics that follow, but I guess grafts are
only computed afterwards, recursively, for the generated profile.

HTH,
Marius

This isn't a problem with the download.

The Guix System installer that you've downloaded is designed to be 
decompressed and written directly to a DVD or USB drive using dd. 
This process is described in detail in the manual[0], including 
the ‘xz’ command to decompress the image.


You'll have more fun if you follow it step by step: don't skip the 
boring ones, and don't add any of your own (like this one ;-)


Good luck!

From the ‘/boot’ in the screenshot, I gathered that they were 
trying to extract the *contents* of the ISO, not the ISO itself 
(or rather, that their ‘helpful’ GUI tool is doing so :-/).


I don't use Gnome, though; is that assumption correct?

Aha, but this is the .iso, not the .tar file.  There's little to 
no point in extracting the ISO.

Sí, me confundí de extensión de archivo por la costumbre, perdón.Tiene que
descomprimir el .iso, acabo de descargarlo para probar y me funcionó en
línea de comandos con `xz -d  guix-system-install-1.0.1.x86_64-linux.iso.xz

made a mistake because of being used to the other file extension, sorry. He

on the CLI with that command (in his case he has to change the filename to
the one he downloaded).

emacs play-sound-file: No usable sound device driver found

[Jeff Bauer]

I've installed emacs 26.2 from the guix package
onto a foreign debian distro.  Mostly everything
appears to work fine, but play-sound-file causes:

"No usable sound device driver found"

I've installed alsa-lib and aplay -l produces:

card 1: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog]

The debian version has no problem playing sound.  Is
there a library install I'm missing?  Thanks.
