I've tried sudo apt-get install build-essential, which results in E: Couldn't find package build-essential

and

sudo apt-get update && sudo apt-get install build-essential which results in several Err http://us.archive.ubuntu.com jaunty-updates/multiverse Sources 404 Not Found [IP: 91.189.88.140 80] and W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/jaunty-security/main/binary-i386/Packages 404 Not Found [IP: 91.189.92.166 80] errors

Any ideas?

Answer 1

Your Ubuntu version is no longer supported by Canonical. Standard archive servers no longer host packages for Jaunty, as Ubuntu (non-LTS) versions are only supported for 18 months, and Ubuntu LTS are only supported for 3 years.

https://wiki.ubuntu.com/LTS:

We produce a new Ubuntu Desktop and Ubuntu Server release every six months [diagram below]. That means you'll always have the latest and greatest applications that the open source world has to offer. Ubuntu is designed with security in mind. You get free security updates for at least 18 months on the desktop and server.

You may use one of miriades unofficial mirrors. Try this search

http://www.google.com/search?q=intitle%3A%22Index+of+%2Fubuntu%2Fdists%22+jaunty

select one on your favor. I'm use http://old-releases.ubuntu.com/ubuntu/dists/, so lines in sources.list seems like

deb http://old-releases.ubuntu.com/ubuntu/ jaunty multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ jaunty multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jaunty-updates multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ jaunty-updates multiverse
