Installation on Ubuntu of qgis

On the latest Ubuntu long term support release (20.04) the LTR long term support version of qgis 3.10 was added. If you are a company looking for long term version of gqis installing qgis from the default ubuntu repositories might not be such a bad idea.

If however you want to install a more recent version of qgis (either latest release or a more up to date LTR version) or possibly are using an older ubuntu version you will need to install qgis from the official qgis repositories.

For smal teams / people happy doing software updated we recommend using the latest version (3.12.x) and this is what this quide will help you doing.

# It happend again the instruction for installing gqis are very hard to understand
# To much formation and half baked scripts and instructions. 
# In my experience .. the people using qgis are not the root/vi type of people
# hence the instructions on that page do not work
# In a similar way they do not work for me becasue TLDR. I want clear
# instructions on doing stuff and specially choosing how to install 
# longer term release is .. bad.
