Installation of proj4 v6 on Ubuntu 18.04 Error: proj/epsg not found

Thanks Edzer,

I removed my gdal (which removes also all QGIS and everything connect
unfortunately) then I followed your steps and I get (somehow the proj
version is still 5 and not 6):

install.packages("rgdal")

Hi Tom,

formerly PROJ.4 is now called PROJ.

Have you also tried the usual ubuntu install suggestions we give to
R/ubuntu users, e.g. on https://github.com/r-spatial/sf ?

They are:

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install libudunits2-dev libgdal-dev libgeos-dev libproj-dev

Dear R-sig-geo,

I am trying to install proj4 v6 on Ubuntu 18.04 bionic. I though I can
install it simply by following the ubuntugis steps
(https://mothergeo-py.readthedocs.io/en/latest/development/how-to/gdal-ubuntu-pkg.html)

but this does not lead to newest version of proj4 v6.

Then I have tried to follow the proj6 steps
(https://proj.org/install.html#install) which indicate that I should do
it via the Anaconda installer. After I installed proj4 v6 from conda
I get:

$ which proj
/home/tomislav/anaconda2/bin/proj

$? proj -V
Rel. 6.2.0, September 1st, 2019
<proj>:
projection initialization failure
cause: no arguments in initialization list
program abnormally terminated

After that I've added the 'PROJ_LIB = /home/tomislav/anaconda2/bin/proj
' to my .Renviron file and then I get:

install.packages("rgdal")
Installing package into
?/home/tomislav/R/x86_64-pc-linux-gnu-library/3.5?

Error: proj/epsg not found
Either install missing proj support files, for example
the proj-nad and proj-epsg RPMs on systems using RPMs,
or if installed but not autodetected, set PROJ_LIB to the
correct path, and if need be use the --with-proj-share=
configure argument.

$gdalinfo --version

What am I doing wrong? Which tutorial / documentation do you advise to
install proj4 v6 and rgdal package on Ubuntu?

thank you (especially you Roger!),
