Ubuntu is a popular distribution of Linux, particularly for desktop use. However, we do not recommend it as a first choice, because we have a site license and management infrastructure for Red Hat Enterprise Linux (RHEL). Our support capabilities and software packaging efforts are focused on RHEL, and we cannot guarantee support for Ubuntu or other distributions.

RHEL is targeted for long-term stability in the enterprise and has a standard 10-year support lifetime that can be extended to 13 years. However, this does have the effect of limiting the use of some newer software, particularly bleeding-edge versions. If you have a need for newer applications that do not work on RHEL, consider using Fedora, the upstream opensource project that is the basis for new versions of RHEL.

If you use any unsupported version of Linux, you are responsible for maintaining security updates. University policy prohibits use of insecure systems on the network.


Standard Ubuntu desktop releases are supported for 9 months. Ubuntu LTS (Long Term Support) releases are supported for 5 years. Any unsupported release must be removed from the university network.

  • To find your release, run this command in Terminal: lsb_release -a
  • To see the support status of your version, run this command in Terminal: ubuntu-support-status

An easy way to test a newer version of Ubuntu for compatibility is trying the Live CD before upgrading.
