No need to suspect, it does. The migration to python 3 of newer
operating systems makes backporting a great deal of software a
nightmare. Similar migrations of the kernel, of the glibc, a of mysql
and httpd and Java, all make it far more adventuresome to support the
old systems.

This has worked well for me several times, with various UNIX and Linux
