fpcupdeluxe does exactly what you're looking for also in Linux/Unix 
environment. It keeps both Lazarus and fpc confined in the folder you 
select, which can of course be in your $HOME directory. The trick for 
Lazarus is quite simple, the icon it puts in your desktop just invokes 
the startlazarus in the folder, with pcp= a configuration file within 
the same folder. The trick for fpc is a bit a hack. As Lazarus requires 
that the name begins with fpc, it passes to Lazarus as fpc compiler an 
fpc.sh script, which sets the fpc configuration and the fpc executable 
in the folder. You'll see it in Tools->Options->Environment.

On Linux I never tried to install in Ubuntu, but I did install in many 
CentOs, Fedora, and Avahi environments. No reason why it should not work 
with Ubuntu. On Raspberry I did install without any problem. Just 
downloaded the appropriate tpcupdeluxe arm version. I installed also on 
the newest Mac with Apple Silicon M1 processor. As it doesn't use 
neither rpm nor apt-get, but just gets the files from svn or git 
repository, the target environment is irrelevant, provided the processor 
architecture is supported.

For cross-compiling you will need to pick up the appropriate options in 
the "cross" tab, after setting the basic options in the "Basic" one. I 
have done it a couple of years ago, to compile and test under Linux and 
then execute on Raspberry, but I don't remember the details. As far as I 
remember it was quite straightforward, with just some Raspberry 
libraries which had to be copied to Linux, in order to link them properly.

The reason for it to propose Lazarus 2.3.0 and Fpc 3.2.4 is that 
fpcupdeluxe doesn't care only about releases, it makes reference to git 
branches and tags. So if you select a released version, or the "Stable" 
one (which is the last release) you get a copy of a stable situation. If 
you select a "work in progress" release, you get the latest snapshot of 
that release. "Trunk" is the most recent one, for both, "Stable"
