Hi,

I'm fighting with guix building:

guix package: error: build failed: the group `"guix-builders"' specified in
`build-users-group' does not exist

# grep guix /etc/passwd
guix-builder1:x:61:479:Guix builder 1:/var/empty:/sbin/nologin
guix-builder2:x:62:479:Guix builder 2:/var/empty:/sbin/nologin
guix-builder3:x:63:479:Guix builder 3:/var/empty:/sbin/nologin
guix-builder4:x:64:479:Guix builder 4:/var/empty:/sbin/nologin
guix-builder5:x:65:479:Guix builder 5:/var/empty:/sbin/nologin
# grep guix /etc/group
guix-builders:x:479:guix-builder1,guix-builder2,guix-builder3,guix-builder4,guix-builder5

Nothing seems to be obviously wrong, but guix ends with this error.

Trying
# su guix-builder1

works as well.

Any ideas?

Best regards,

Tomas Cech

Hmm, what does “getent group guix-builders” return?
And “getent passwd guix-builder1”?

How did you create the accounts?

Thanks for the report,

So that’s all good.

The daemon simply does that (build.cc):

Toggle snippet (7 lines)
/* Get the members of the build-users-group. */
struct group * gr = getgrnam(settings.buildUsersGroup.c_str());
if (!gr)
throw Error(format("the group `%1%' specified in `build-users-group' does not exist")
% settings.buildUsersGroup);

Can you try getgrnam("guix-builders") in C or some other language (from
Guile: (getgrnam "guix-builders")) ?

Does it make a difference if nscd is stopped or restarted?

Thanks,
Ludo’.

scheme@(guile-user)> (getgrnam "guix-builders")
$2 = #("guix-builders" "x" 479 ("guix-builder1" "guix-builder2" "guix-builder3" "guix-builder4" "guix-builder5"))

No, it behaves the same with or without running nscd.

Thanks,

Then there’s something weird: Guile’s getgrnam directly corresponds to
libc’s getgrnam(3), which is what guix-daemon uses in the snippet above.

Oh, I see the error message you gave above reads:

the group `"guix-builders"'

Note the extra double quotes.

Could it be that the script that launches guix-daemon does something
that amounts to:

guix-daemon '--build-users-group="guix-builders"'

That is, it leaves the double quotes as is in the argument?

Thanks,
Ludo’.

It seems to be that case. Thank you and sorry for the noise...
