I am trying to install Pygobject on my 64-bit Ubuntu 16.04 by following instructions given here: https://python-gtk-3-tutorial.readthedocs.io/en/latest/install.html
It recommends using jhbuild to build pygobject. So I install jhbuild (something I've never seen before following instructions given here: https://developer.gnome.org/jhbuild/unstable/getting-started.html.en) which worked out fine.
Initially I had to run jhbuild sysdeps --install to install missing dependencies which took a LONG time. After it was done it said Nothing to install which I presume means it found everything it needed.
Then the
jhbuild bootstrap command said *** success *** [1/1]. OK.
The jhbuild sanitycheck gives no output, (supposedly) meaning all is well.
Then, I run the command jhbuild build pygobject and get error:
Checking if "C_IN in public headers (no arpa/nameser_compat.h needed)"
compiles: NO
Checking if "arpa/nameser_compat.h needed for C_IN" compiles: NO
gio/meson.build:35:6: ERROR: Problem encountered: Could not find
required includes for ARPA C_IN
A full log can be found at

[1] Rerun phase configure
[2] Ignore error and continue to build
[3] Give up on module
[4] Start shell
[5] Reload configuration
[6] Go to phase "wipe directory and start over"
choice:
Doesn't matter what I choose, it either ends the build or gives errors like the following, if I choose [2]:
*** Building glib *** [6/10]
ninja
ninja: error: loading 'build.ninja': No such file or directory
*** Error during phase build of glib: ########## Error running ninja
*** [6/10]
.
.
.
and then
configure: error: Package requirements (glib-2.0 >= 2.57.1) were not met:
Requested 'glib-2.0 >= 2.57.1' but version of GLib is 2.48.2
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GLIB_CFLAGS
and GLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
*** Error during phase configure of gobject-introspection: ########## Error running /home/anshulvj/jhbuild/checkout/gobject-introspection/autogen.sh --prefix /home/anshulvj/jhbuild/install --disable-Werror --with-python=python3 --disable-static --disable-gtk-doc *** [9/10]
Which is weird because I cannot find anything related to installing glib2.57 or greater online. (https://github.com/GNOME/glib)
The documentation at https://python-gtk-3-tutorial.readthedocs.io/en/latest/install.html does not deal with these errors and I'm completely lost. I googled a lot but did not find anyone who was facing the same issue. If this does not work I'm going to give up on Python3+GTK3+.
Any help/pointers are appreciated.
EDIT: Today I tried installing based on instructions given here https://pygobject.readthedocs.io/en/latest/getting_started.html using pip. It doesn't matter if I use pip or pip3 I get the following error.
