[Bug 1845187] Re: Can't install 'lubuntu-desktop' during upgrade to 19.04 from Lubuntu 18.04

[Chris Guiver]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

The Lubuntu desktop in 18.04 LTS was LXDE, later lubuntu-desktops use
LXQt which must be clean installed (not upgraded). This was noted in the
18.10 release notes, ie. https://lubuntu.me/cosmic-released/

"The most major and notable problem is that upgrading Lubuntu from 18.04
to 18.10 causes a fair amount of issues. Therefore, we are not
officially supporting this upgrade path at this time, however we have
prepared a page in the Lubuntu Manual which can help address the
problems that arise after the upgrade."

There have been no changes with 19.04 (https://lubuntu.me/disco-
released/), the upgrade path from 18.10 was good, but it was not
supported from 18.04 LTS (or LXDE).

Because of this unsupported path, I've changed the status to invalid.
If you believe I'm in error, please leave a comment as to why and change
it back to "New".  The upgrade path from 18.04 LTS to 20.04 LTS may
still be possible without clean install, but it's currently unsupported
from 18.04 to 18.10/19.04/19.10 (possible yes, but problems may occur
thus the unsupported status).

** Changed in: ubuntu-release-upgrader (Ubuntu)
       Status: New => Invalid
