Is it 'safe' to upgrade Ubuntu Server with hashcat?

[baglock]

So yes, you can safely update the OS.

Indeed it worked just fine. Thank you sir, and thank you for the speedy reply.

And now a follow up stupid question to my first stupid question....

If and when I add an additional video card, will Hashcat (Catalyst) recognize it right away or do I need to re-kick something to see the new card? I wold try it myself but I don't have another card around here...yet.

Thanks.
