Hello,

I wanted to install python, numpy and conda on plafrim as explained here : https://www.plafrim.fr/en/guix/
And guix pull failed :

    guix package -i python python-numpy python-conda

    eval `guix package --search-paths=prefix`

    guix pull

I want to precise it is my first time with guix and I may misunderstood some points...

Could you post the lines preceding this error message? I just experienced
a similar case, and the real error happened before (a package needed to be
compiled first and failed).

Could you please send the output of
   guix --version
and
   guix describe
?

Thanks,

Andreas

This looks like nscd is not running.

The manual says this:

    2.6.2 Name Service Switch
    -------------------------

    When using Guix on a foreign distro, we _strongly recommend_ that the
    system run the GNU C library’s “name service cache daemon”, ‘nscd’,
    which should be listening on the ‘/var/run/nscd/socket’ socket.  Failing
    to do that, applications installed with Guix may fail to look up host
    names or user accounts, or may even crash.

Could you check that NSCD is in fact available and running?

Hello,

I rolled back all my generations (I hope this is good - with command guix package --roll-back)

$ guix package -i python python-numpy python-conda
Les paquets suivants seront installés :
   python	3.7.0	/gnu/store/9z98cvjm7p7z21xdid1ryydxy5vyz6wr-python-3.7.0
   python-numpy	1.15.4	/gnu/store/hsdzxq5jvb96yffnxqp8h4lq5z59r29k-python-numpy-1.15.4
   python-conda	4.3.16	/gnu/store/gabw5n3216xzbbsjsc5j5vhjpninanyh-python-conda-4.3.16

$ eval `guix package --search-paths=prefix`

It seems there is no issue.

nscd seems to be launched. I am not admin on the server.
$ ps aux | grep nscd
vrou001   25642  0.0  0.0 112688   976 pts/37   S+   17:46   0:00 grep --color=auto nscd
nscd     135028  0.0  0.0 768500  4020 ?        Ssl  févr.11   2:17 /usr/sbin/nscd

Maybe this is not a guix bug but a server issue.
Sorry for the noise, I will see with the admin.

Regards,

Vincent Rouvreau

This is likely related to <https://bugs.gnu.org/30298>.

If so, the solution is to either use nscd, as Ricardo suggested, or to
edit '/etc/nsswitch.conf'.

Actually nscd *is* running but it’s been misconfigured on these machines
since a couple of weeks or so—the sysadmins are aware of it and will
take a look shortly.

What happens is that nscd returns nothing for “passwd” database lookups
and as a result, the application (in this case Guile) falls back to its
local NSS implementation, which in turns tries to load an incompatible
libnss*.so file, leading to this lookup failure.

Anyway, this really looks like a setup issue on this machine, so I’m
closing this bug and we can discuss it further with the admins if
needed, Vincent.

Thanks,
Ludo’.
