Open CPN on ubuntu?

'nother noobie Mint question.

I am running Linux Mint 14 and have managed to get my head around installing OpenCPN. After much searching, I've discovered that the plugins need to copied to usr/lib/opencpn and when I try do that, it won't let me because I don't have permission to write to that folder. How do I change the permissions of that folder without screwing things up?

Thanks.
 
Thanks for the quick reply. This worked:
sudo chmod 777 /usr/lib/opencpn
 
Thanks. I've since rebooted and the permissions went back to the default. Wish I knew more about how that happened.
