</div></div>Hey,<br>
<br>
>From this output, it seems that the failure is in pulling the<br>
"qtubuntu-desktop" package. This package still exists in xenial and is<br>
in the universe pocket.<br>
This is failing for you because it seems that universe isn't enabled in<br>
your system sources.list. Do you mind checking this? "apt-cache policy<br>
qtubuntu-desktop" should returns some packages to you<br>
<br>
Cheers,<br>
Didier<br>
