reinstalling gdal, and R raster, sf, stars

As a geoscientist working a lot with R, I just had another worst-day-ever installing GDAL and PROJ. Python is less problematic because you can always have everything clean in your conda environment.

With R, you can do a docker, but not as convenient.

if you managed with gdal, e.g. sf, stars, rgdal all works, but not raster, then you probably need to reinstall the package “terra”! I tried many things with my gdal but this comes to a rescue.

The gdal probelm happens probably more often with LINUX because with windows the cleaning up/ uninstalling is easier.

The problem was I had a gdal 3.4, it is incompatible with some software, so I installed a gdal 2.4, then of course the PROJ will complain. Then I started a loop of removing – reinstalling – manually fixing gdal-config file – manually removing and downloading things – searching for solutions – try – try -try

But the problems are just endless. And things just got all messed up. Well, you still learn something, you learn more about gdal, but nothing useful.

All I need is a clean-wash of all gdal things. This blog comes to rescue.

But sudo apt-get --reinstall install gdal-bin never cleans things up.

So what you need to do is:
sudo apt-get purge --auto-remove libgdal
sudo apt-get purge --auto-remove libgdal29
sudo apt-get purge --auto-remove gdal-bin
sudo apt-get purge --auto-remove libkml-dev
sudo apt-get purge --auto-remove libproj-dev

apt-get install libgdal-dev gdal-bin libproj15 libproj19 libproj-dev

a trick for the "sf' package is 
sudo ln -s /usr/lib/x86_64-linux-gnu/ /usr/lib/

I gave full credit to the excellent post:

I hope now it is the end of my gdal-headache.
