Question

I've been having a lot of problems with this install, especially with various unmet dependencies. these are my system infos:

Linux

• Ubuntu 20.04.4 LTS
• 64-bit
• Gnome_Version: 3.36.8

Python

• using a "poetry environment" (uses pip)
• python Version: 3.8.10

Answer 1

I was finally able to install it more or less cleanly and get it working across the board and hope it will be usefull for others:

Installing GDAL on linux is full of problems and issues - this has resolved some of them for me:

sudo apt install libpq-dev 

problem depedency with libpq5

sudo apt install libpq5=12.2-4

sudo apt install libpq-dev 

success!

sudo apt install gdal-bin

sudo apt install libgdal-dev 

problem with LOTS of dependencies

sudo apt install aptitude 

(aptitude can help resolve dependency problems)

sudo aptitude install libgdal-dev 

asks how to resolve issues --> I changed to next reccomendation by pressing "." --> then confirmed by pressing "Y" -->success

after these steps are successfull check if all 3 main libs are installed: "libpq-dev, gdal-bin, libgdal-dev":

apt list --installed | grep "gdal"

result:

---

check gdal version (should be 3.3.2 or higher if all went well):

gdalinfo --version

PYTHON

to install gdal in a python environment should now be possible:

poetry add gdal==3.3.0

or

pip install gdal==3.3.0
