Fatrat not work, this is the error message: fatrat
fatrat: error while loading shared libraries: libboost_system.so.1.65.1: cannot open shared object file: No such file or directory

There is no fatrat on the test ISO, and it is known that fatrat won't run in the [build] repo where boost 1.66 is now. Fatrat will be removed from the repos, it is dead upstream, the build fail now on new boost is the last straw. See the release notes from this test ISO when you start the installer, is it already announced it is being replaced.

Closing this topic since it has nothing to do with the test ISO, or any of the sections you placed this topic under.
