I just got a Mac mini that I will use to play FLAC-files in my stereo (DAC to be bought). I have no idea how old it is. Might be from 2010?

However, I have problems reinstalling it. There's a sticker on the back that says: MAC OS X 10.6 SRV UNLIMITED CLIENT

The install stops after a while saying: No packages were eligible for install. contact the software manufaturer for assistance ...I'm doing a network install recovery.

It seems like this problem could have something to do with the date?

I tried setting the date to 2017 (some sources claimed that this would to the trick) by starting in Single user mode. But I get this: Common missing bluetooth controller transport...

And can't even type in the terminal. Any ideas on how to restore this?
