Try compile delphimodbuslazarus in linux.
Indy components installed (with problem too, but i can install it).

"Compile" package - no problem, but then click "Install":
delphimodbuslazarus.pas(10,5) Fatal: Cannot find IdModBusClient used

ts/delphimodbus/packages/lib/x86_64-linux/IdModbusClient.ppu, package
DelphiModbusLazarus

What am I doing wrong?

Linux file system is case-sensitive. Make sure the .ppu is either all
lower case or else matches exactly the case specified in any unit that
uses it.

For the experiment change case to lower (file name, and all text entry
in files).

without changes:

Try use just "Indy". Same problem:
formmain.pas(20,3) Fatal: Cannot find IdComponent used by FormMain,
incompatible ppu=/usr/lib/lazarus/1.6/components/indy/lazarus/lib/x86_
64-linux/IdComponent.ppu, package indylaz

Then drop indy component to form show message  "Press OK to ignore and
risk data corruption." and IDE is falling.

Anybody used "indy-10.2.0.3" in Linux?

DelphiModbusLazarusI had a lot of these errors when working with my
initial version of the TvPlanit components where several packages
shared the same source folder, i.e. several lpk files along with all
source files. This may work for some time, but suddenly, after a
little change, the packages will not install any more. The safest way
to resolve this problem is to keep the individual packages (along with
their sources) separately in different folders.

Where is that package from?
https://sourceforge.net/projects/delphimodbus/?source=typ_redirect? In
this case, there is only one package, and only a few source files, and
I think the explanation above is not valid here. But possibly Lazarus
finds compiled files at places where they should not be. This will
result in the same error message. Delete all compiler-generated files
and try again. Try a clean build of Lazarus ("Tools" / "Configure
Build Lazarus" / "Clean all" - check "Switch after building to
automatic"). Compiler-generated files should only be in the lib
folders of the packages (sometimes also labeled "units").

I had serious problems compiling indy with FPC because of the
duplicate includefiles.

As soon as I deduplicated the includefiles, the problem went away.

The latest trunk seems to have gotten rid of this include file mess
away. I was able to compile it in one go.
