[Lazarus] Install Lazarus 2.2.4 on Ubuntu 20.04 LTS and other Linux

[Bo Berglund]

Need help after fpc/lazarus moved from subversion...

So I have been using Lazarus/FPC on Linux for a long time now (12+ years) and I
have installed from sources using subversion access to the release tags on the
source svn server.
I created a script I could use on all these platforms to do the complete
installations of fpc, lazarus, dependencies and custom components etc.

This has been done on various Linux distros like Ubuntu 14-16-18-20 and
RaspberryPi since about 2014 until 2020 or so.

Now after having paused my programming a bit over the Covid pandemic I am back
and need to update my installations by adding the newest version 2.2.4.

But meanwhile the subversion server I have used has been replaced by some other
versioning system so my script does no longer work...

So I am asking how can I install from scratch on Linux (Ubuntu on PC and PiOS
for RaspberryPi) in such a way that the older versions can remain in place?

I googled a bit and found references to some deb files to download and use as
sources, but then was also stated that installing one version would remove any
other (earlier or later) existing version, which I surely do not want.

I need the 2.2.4 version to exist in parallel with my older versions 2.0.6,
2.0.8, 2.0.10 and 2.0.12, so I can still build my applications with either of
them...

Please advice!

PS
I also have Lazarus installed on Windows-10 but this is done using the official
sourceforge installers (i.e. not from source) and has resulted in separate
installations for these versions so I can build my code also for Windows.
