No real surprises there... though the sourceforge page is still up, but no updates in nearly a year. Looks dead.
Actually this is (wasn't?) a *BSD or a "FreeBSD derivative" -
it was in fact a "GNU" and it seemed to be based on this:
https://www.debian.org/ports/kfreebsd-gnu/
(...and maybe some ported Ubuntu Linux packages. But the desktop is Xfce, so probably not that much to port...)
The name "UbuntuBSD" was in itself misleading. It may be partially Ubuntu based, as with Linux Mint, etc, but the distribution in itself is a derivative of
Debian GNU/kFreeBSD. Regardless, that actually makes it a "GNU" with a (modified) FreeBSD kernel. Pretty much none of the FreeBSD base system, ports or package tools are included.
In "Linux land" it seems that you just need to build a few packages, think up a name, design a logo and immediately you have another addition to the many thousands of distributions... this is just yet another short lived "Linux land" (without the Linux) spin off.
And in the blurb on sourceforge site, we learn that it's "Your replacement for Ubuntu without SystemD"...
'Easy to use'/install FreeBSD based OS for x86 desktop, etc:
