Starting apache fails (could not bind to address 0.0.0.0:80)

Question

Update: Already fixed, it seems that one of VirtualHosts configurations files was wrong in sites-enabled.

I have Ubuntu 11.10

When I run the command to start

Answer 1

It look like other process is using port 80.

$ netstat -anp | grep

eg. $ netstat -anp | grep 80

by above you get process name, if you want to use port then you need to stop the process or change the port
