Dear Paul,
Yes, you're right, I just downloaded the .deb from the page of the project and then installed with Gdebi. After installation Gdebi shown the possibility to upgrade (I think) and I given the "install" command again. Then there was the problem.
The Italian statement:ErrorMessage: tentata sovrascrittura di "/usr/share/fpcsrc/3.0.0/rtl/android/jvm/java_sys_android.inc" presente anche nel pacchetto fpc-src 3.0.0  InstallationDMeans: tried to overwrite "/usr/share/fpcsrc/3.0.0/rtl/android/jvm/java_sys_android.inc" present also in the package fpc-src 3.0.0
I reported this just in case could help you.
Thanks in any case for your commitment in those issues,
Regards,
Simone Bonzanini

I may be mistaken (I don't understand Italian (or whatever the language
is)), but it seriously looks like you installed the Debian package from
upstream and then tried to upgrade with the package in Ubuntu. I am
terrible sorry to say that in general that is impossible to support.

In this case, I will try to fix it, but that fix will NOT go into Xenial
Xerus as that is already frosen.

The Debian/Ubuntu package callled fpc-src never contained any files, it
was always a meta package.

** Summary changed:

- package fpc-source-3.0.0 (not installed) failed to install/upgrade: tentata sovrascrittura di "/usr/share/fpcsrc/3.0.0/rtl/android/jvm/java_sys_android.inc" presente anche nel pacchetto fpc-src 3.0.0
+ please make sure that the Debian/Ubuntu package replaces the package provided by upstream

** Changed in: fpc (Ubuntu)
