I'm just starting out with Raspberry Pi. Following the instructions to set up a security camera (Link) all goes well until the command: sudo lighty-enable-mod fastcgi-php and I get the message: sudo: lighty-enable-mod: command not found. Despite searching far and wide I can't get any clues to what is going on. Help!?

Output from "sudo apt-get -y install lighttpd":

E: There are problems and -y was used without --force-yes

  • Are you sure you installed lighttpd package without errors? Can you paste output of: sudo apt-get -y install lighttpd ? – Huczu Apr 29 '16 at 10:29
  • Good question Huczu. I've posted the output above. What do you think? – BillP Apr 29 '16 at 12:03

There is an error with -y parameter Simple use:

sudo apt-get install lighttpd

and accept when he ask to install or try to use

sudo apt-get -y --force-yes install lighttpd
  • Thank you. It ran without error. I then saw that I had a similar E: message in the next command (sudo apt-get -y install php5-common php5-cgi php5) so tried that without the -y. I got a five E: messages (one was "E: Failed to fetch mirrordirector.raspbian.org/raspbian/pool/main/p/php5/… 404 Not Found [IP: 80]") and a final one: "E: Unable to fetch some archives, maybe run apt-get update or try with --fix-mis". I clearly need to understand the basics of all this better. Is there a reference that you can suggest? Thanks again. – BillP Apr 30 '16 at 0:50
  • This turned out to be a beginner's error of not updating - which solved the problem. – BillP Apr 30 '16 at 5:40
