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) Assignee: (unassigned) => Paul Gevers (paul-climbing) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1568072 Title: please make sure that the Debian/Ubuntu package replaces the package provided by upstream To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fpc/+bug/1568072/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
