LXDE apt-get fails 404 Error

[Altera_Forum]

Hi, 

 I am using the LXDE image from the terasic website. When I do apt-get update, it fails with 404 errors. It is not a connectivity issue (I can connect to the internet). I believe it to be a problem in the /etc/apt/sources.list file, which currently contains:   deb http://ports.ubuntu.com/ubuntu-ports/ quantal main universe deb-src http://ports.ubuntu.com/ubuntu-ports/ quantal main universe    The error I get is:   Err http://ports.ubuntu.com quantal/main Sources 404 Not Found Err http://ports.ubuntu.com quantal/universe 404 Not Found Err http://ports.ubuntu.com quantal/main armhf Packages 404 Not Found etc...   Is there a way to fix this so that apt-get actually functions?   Thanks, Mike

After some further digging around I managed to fix this problem properly:- 

 Delete all lists of downloaded packages:-  cd /var/lib/apt/lists rm *  Update package lists:- apt-get update  Upgrade:- apt-get upgrade Probably libssl1.0.0 will be upgraded from 1.0.1c-3ubuntu2.5~linaro1 to 1.0.1c-3ubuntu2.5~linaro2  Optional, Install SSH & change passwd:  apt-get install openssh-server passwd
