[Bug 1768949] Re: cannot upgrade

[Brian Murray]

A better solution would be to install the 'lubuntu-core' package which
is a meta-package and try the release upgrade again. From Mainlog.txt we
can see:

2018-05-04 01:57:33,036 DEBUG none of the '['ubuntu-desktop', 'kubuntu-desktop', 'xubuntu-core', 'xubuntu-desktop', 'ubuntustudio-desktop', 'mythbuntu-desktop', 'kubuntu-netbook', 'lubuntu-core', 'lubuntu-desktop', 'ubuntu-gnome-desktop', 'ubuntu-mate-core', 'ubuntu-mate-cloudtop', 'ubuntu-mate-desktop', 'ubuntukylin-desktop']' meta-pkgs installed
2018-05-04 01:57:33,037 DEBUG guessing 'lubuntu-core' as missing meta-pkg
2018-05-04 01:57:33,085 DEBUG marked_install: 'lubuntu-core' -> 'True'
