Hi Harrissou,
Sorry, I was just assuming that question was related to Windows (where
>90% of our user base is).
On Linux it is more complicated. To do that on Linux, I compile QGIS
from source myself. Than it is possible with different start scripts
that have different library paths.
There may be other ways to install both versions from binaries on Linux
that I am not aware of.
There were discussions about supporting Snap or flatpack packages in the
future - but they don't exist yet. This may be a way to install both
versions on Linux as well.

Hi Strumbi,
They can be installed and run in parallel.
Easily?
I could do that on Windows or macOS but never succeeded on Linux
(tried with 2.14 and 2.18 in the past and ended up with building from
source the latest version, unless there is a difference in 2.x vs 3.x).
What would then be the steps/requirements to use the provided packages
and build different versions of QGIS on the same machine (nota: i'm
still a beginner on Linux).
Thanks,
Harrissou
They have independent settings.
The only restriction is: once you have saved a project in QGIS 3,
there may be no way back to 2.18.
The other thing to watch out is plugins or Python code: plugins
and Python code from QGIS 2.x don't run in QGIS 3.x. They have to
be revised because of the change from Python 2 to Python 3 and qt4
to qt5. In addition, the QGIS API changed considerably.
Theoretically, a plugin can be written to work in both QGIS 2 and
QGIS 3, but in practice, such plugins don't exist very often.
Greetings,
Andreas

Hello
I apologize if this question has been asked already. Should I
uninstall QGIS 2.18 before I install QGIS 3.
Thank you
