Title: Canonical now requires an Ubuntu Pro subscription to get security updates, even for Ubuntu releases that are still supported. On an Ubuntu 22.04 system that&#x27;s not subscribed to Ubuntu Pro, the output of running &quot;sudo apt dist-upgrade&quot; includes this:<p><pre><code>  The following security updates require Ubuntu Pro with &#x27;esm-apps&#x27; enabled:
    libopenexr25 libmagickcore-6.q16-6-extra libmagickwand-6.q16-6
    libmagickcore-6.q16-6 imagemagick-6-common
