I use Ubuntu through a virtual machine (VM Workstation Player) and sometimes download packages through the terminal. Some of the packages I download are not the latest version. For example, I downloaded Eclipse IDE and Wireshark and some versions were downloaded. Even when I try to update those packages, it tells me that the packages are up to date.

Why can't I download the latest versions and how can I fix this?

Some Linux distributions (distros) are more "conservative" or "prudent" than others and prefer to use more stable versions of packages, meaning you won't be able to download the latest versions through the standard repositories.

If you want the latest version of some softwares, you'll have to use alternative repositories by installing a Personal Package Archive (PPA) on your Ubuntu distro.

For instance, If you want to use the latest version of LibreOffice, you'll have to install this PPA:

https://launchpad.net/~libreoffice/+archive/ubuntu/ppa

Be careful to install only trusted PPA, coming from reliable sources (see Are "PPA's" safe to add to my system, and what are some "red flags" to watch out for?).

To install a PPA, you can:

  • add a line to the sources.list file in /etc/apt. For LibreOffice, it's deb http://ppa.launchpad.net/libreoffice/ppa/ubuntu wily main
  • on a terminal, type sudo add-apt-repository ppa:libreoffice/ppa
