You would have had to force the upgrade, which is not recommended. The<br>
upgrade path from 18.04 LTS to 20.04 LTS will only be available when<br>
20.04.1 is out (June?). There are a lot of web sites out there that<br>
blithely tell you if the do-release-upgrade command does not work,<br>
just add the -d option to make it work. They completely fail to<br>
explain that the upgrade is not working because it is not supposed to<br>
be working yet. Adding -d allows you to upgrade on the basis that<br>
20.04 is a development version for upgrading 18.04 LTS, not a release<br>
version. So anyone doing that should be prepared for problems. That<br>
said, I have not heard of any show stopper problems from anyone who<br>
has forced the upgrade, unlike what happened with 16.04 LTS to 18.04<br>
LTS before the .1 update was out.<br></blockquote><div><br></div><div><br></div><div>Indeed, I forced the upgrade and only share in case anyone else likes to live on the edge.</div><div><br></div><div>An alternative workaround to specifying the i965 driver is to add the following to the device section of xorg.conf:</div><div><br></div><div>Option "DRI" "3" <br></div><div><br></div><div>The problem appears to be a known issue with intel UHD500 / latest Mesa and intel driver (<a href="https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel/-/issues/193">https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel/-/issues/193</a>). </div><div><br></div><div>Hopefully will be fixed soon.</div><div><br></div><div><br></div></div></div>
