I thought I'd keep going with the perfect server 16.10 install just to see if the rest works and... oops! The build of jailkit fails. I edited the file as per instructions, ran./debian/rules binary and got a badly formed line 15. Couldn't see a fault with it but, well, ok, lets have another go. I deleted the tmp jailkit directory and started again with the wget. Made the amendment to changelog and it still won't build. Can't see anything wrong with my edit but nope, won't have it. Any ideas please? p.s. I've not put the file in here 'cos it really is identical to the one in the how-to.
