When we launched Ubuntu LTS, we made a commitment to security-support these packages and their dependencies in 'Main' for five years, free of charge. There were initially about 1,000 packages in 'Main', and today that number has grown to about 2,300 per Ubuntu release. </p> <p> The 'Universe' repository holds all of the other open source packages in Ubuntu, from Debian and the Ubuntu community. Universe is a much bigger repository of over 36,000 packages per release (as of Ubuntu 24.04 LTS). This includes packages for open source toolchains and libraries like Java, Php, GO, Python and others. </p> <p> With the launch of Ubuntu Pro, all of the packages in Ubuntu Universe get the same security maintenance commitment from Canonical as packages in Ubuntu Main. </p> <div class="p-cta-block"> <a href="https://discourse.ubuntu.com/t/ubuntu-pro-faq/34042">Check out the Ubuntu Pro FAQ &rsaquo;</a> </div> </div> </div> </section> <section class="p-section"> <div class="p-section--shallow"> <div class="row--50-50"> <hr class="p-rule" /> <div class="col"> <div class="p-section--shallow"> <h2>Benefits of Ubuntu Pro</h2> </div> </div> <div class="col"> <ul class="p-list--divided"> <li class="p-list__item is-ticked">Gain peace of mind</li> <li class="p-list__item is-ticked">Keep systems stable and maintained</li> <li class="p-list__item is-ticked">Reduced need for migrations</li> <li class="p-list__item is-ticked">Proactive Ubuntu Security Team</li> <li class="p-list__item is-ticked">Get quick fixes to critical, high and selected medium CVEs</li> <li class="p-list__item is-ticked">Maintain compliance across your estate</li> </ul> </div> </div> </div> <div class="u-fixed-width"> <div class="p-image-container--cinematic is-cover"> <img src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,w_2464,h_1028/https://assets.ubuntu.com/v1/a7dc8f0d-benefits-of-ubuntu-pro.png" srcset="https://res.cloudinary.com/canonical/image/fetch/c_limit,f_auto,q_auto,fl_sanitize,w_4928,h_2056/https://assets.ubuntu.com/v1/a7dc8f0d-benefits-of-ubuntu-pro.png 2x" alt="" width="2464" height="1028" loading="lazy" class="p-image-container__image" /> </div> </div> </section> <section class="p-section"> <div class="row--50-50"> <hr class="p-rule" /> <div class="col"> <div class="p-section--shallow"> <h2> The difference between <br /> 'esm-apps' and 'esm-infra' </h2> </div> </div> <div class="col"> <p> Ubuntu Pro is a broad subscription that includes many different variations of open source packages to meet different needs. For example, Pro includes a set of package versions that are compliant with FIPS regulations. You would want these versions only on machines that need to meet FIPS requirements, so you can choose to enable that stream specifically on those machines. </p> <p> There are two streams which cover broad-based package security updates; we label these “apps” and “infra”. The “esm-apps” stream covers all 'Universe' packages for ten years from the release of the LTS. </p> <p> The “esm-infra” stream covers 'Main' packages for the period after the standard five year security maintenance of 'Main' packages ends. We call this 'infra' because it is commonly used to build our private cloud, storage and kubernetes clusters, where 'Universe' packages are not typically deployed. You can get a lower-cost Ubuntu Pro (infra-only) subscription if you only want the infra components, which equates to our original ESM offering. </p> <div class="p-cta-block"> <a href="/security/contact-us" class="js-invoke-modal">Get in touch &rsaquo;</a> </div> </div> </div> </section> <section class="p-section"> <div class="p-section--shallow"> <div class="row--50-50"> <hr class="p-rule" /> <div class="col"> <h2>What is covered?</h2> </div> <div class="col"> <p> ESM continues security updates and <a href="/security/livepatch">kernel livepatching</a> for high and critical CVEs (Common Vulnerabilities and Exposures). </p> </div> </div> </div> <div class="p-section--shallow"> <div class="u-fixed-width u-esm-overflow-table"> <table class="p-table"> <thead> <tr> <th width="25%">Release</th> <th width="25.5%">All packages in 'main' repository</th> <th width="25%">All packages in the 'universe' repository</th> <th width="10%">Kernel Livepatch</th> <th>Architectures supported with ESM</th> </tr> </thead> <tbody> <tr> <td>Ubuntu 14.04 LTS (Trusty Tahr)</td> <td>May 2026</td> <td>n/a</td> <td>amd64</td> <td>amd64</td> </tr> <tr> <td> <a href="/16-04">Ubuntu 16.04 LTS (Xenial Xerus)</a> </td> <td>May 2028</td> <td>May 2028</td> <td>amd64</td> <td>amd64, s390x</td> </tr> <tr> <td> <a href="/18-04">Ubuntu 18.04 LTS (Bionic Beaver)</a> </td> <td>May 2030</td> <td>May 2030</td> <td>amd64</td> <td>amd64, arm64, s390x, ppc64el</td> </tr> <tr> <td> <a href="/20-04">Ubuntu 20.04 LTS (Focal Fossa)</a> </td> <td>May 2032</td> <td>May 2032</td> <td>amd64</td> <td>amd64, arm64, s390x, ppc64el, RISC-V</td> </tr> <tr> <td>Ubuntu 22.04 LTS (Jammy Jellyfish)</td> <td>May 2034</td> <td>May 2034</td> <td> amd64, <br /> s390x </td> <td>amd64, arm64, s390x, ppc64el, RISC-V</td> </tr> <tr> <td>Ubuntu 24.04 LTS (Noble Numbat)</td> <td>May 2036</td> <td>May 2036</td> <td> amd64, <br /> s390x </td> <td>amd64, arm64, s390x, ppc64el, RISC-V</td> </tr> </tbody> </table> </div> </div> <div class="p-section"> <div class="p-section--shallow"> <hr class="p-rule--highlight is-fixed-width"> <div class="row"><div class="col-3 col-medium-2"> <h2 class="p-muted-heading">What our customers say</h2> </div></div> </div> <div class="row"> <div class="col-9 col-start-large-4 col-medium-4 col-start-medium-3"> <hr class="p-rule--muted"> <div class="row"> <div class="col-6"> <div class="p-section--shallow"> <p class="p-heading--4"> <i> “Keeping all software maintained is expensive, and hiring new developers with proficiency in older versions of PHP can be very expensive and difficult.” </i> </p> </div> </div> <div class="col-3"> <hr class="p-rule--muted u-hide--large"> <p> <strong>Spokesperson</strong> <br> <span class="u-text--muted"> Games publishing company </span> </p> </div> </div> <div class="p-cta-block"> <a href="https://canonical.com/case-study/ubuntu-pro-support-for-games-developer">Read the full case study &rsaquo;</a> </div> </div> </div> </div> <div class="u-fixed-width"> <div class="p-image-container--cinematic is-cover"> <img src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,w_2464,h_1027/https://assets.ubuntu.com/v1/633150af-servers.png" srcset="https://res.cloudinary.com/canonical/image/fetch/c_limit,f_auto,q_auto,fl_sanitize,w_4928,h_2054/https://assets.ubuntu.com/v1/633150af-servers.png 2x" alt="" width="2464" height="1027" loading="lazy" class="p-image-container__image" /> </div> </div> </section> <section class="p-section--deep"> <div class="row"> <hr class="p-rule" /> <div class="col-3"> <div class="p-section--shallow"> <h2>Learn more</h2> </div> </div> <div class="col-9 col-medium-6"> <div class="p-section--shallow"> <div class="row"> <div class="col-3 col-medium-3"> <h3 class="p-heading--5">Ubuntu 18.04 LTS out of standard security maintenance</h3> </div> <div class="col-6 col-medium-3"> <p> Ubuntu 18.04 LTS Bionic Beaver, one of the most popular Ubuntu releases, has reached the end of standard support.
