Installation Error

[ReionX]

When ever i try to install a Counter Strike Server i get:

terminate called after throwing an instance of 'CryptoPP::OS_RNG_Err'
what(): OS_Rng: read /dev/urandom operation failed with error 21
Aborted

And i cant find anythink in google about this error, or anythink that realy helped.

Am i doing somthink wrong or do i need to do somthink befor this?

Thanks,
Ryan

I've never seen such thing in my life and it makes no sense to me at all...
