How do I apply a security update to apache
Solution 1:
Try this
sudo -i
gedit /etc/apt/sources.list
add the line
deb http://us.archive.ubuntu.com/ubuntu/ precise main
Save and exit, then do
sudo apt-get update
sudo apt-get install apache2
apache2 -v
Then edit /etc/apt/sources.list again, and comment out or delete the following line completely
#deb http://us.archive.ubuntu.com/ubuntu/ precise main
sudo apt-get update
