Can't build nix on Ubuntu 16.04

[popey]

Tried form tip of git and from a 1.11.2 release tarball. Both end the same way:-

$ make
GEN Makefile.config
GEN doc/manual/version.txt
GEN doc/manual/manual.xmli
GEN doc/manual/manual.is-valid
I/O error : Attempt to load network entity http://docbook.org/xml/5.0/rng/docbook.rng

Dirty workaround would be to remove occurrences --nonet from doc/manual/local.mk

[vcunat]

Why not use our debs directly, at least as a work-around? #892 (comment)

[armijnhemel]

Can this one be closed, because #1066 has been merged?

[popey]

I just tried nix-1.11.9 snapshot, and tried the option referenced in #1066 but maybe I'm holding it wrong?

alan@gort:~/Development/nix/nix-1.11.9$ ./configure --prefix=/usr/local --disable-doc-gen
configure: WARNING: unrecognized options: --disable-doc-gen

[armijnhemel]

It seems that this fix was not applied to the 1.11-maintenance branch, just to master. Adding @edolstra

I/O error : Attempt to load network entity http://docbook.org/xml/5.0/rng/docbook.rng

@popey Try

sudo apt-get install docbook-xsl-ns

to fix that one, worked for me on Ubuntu 16.04. See #506 (comment)

PR to fix it #2979
