lubuntu mantic install (unclean) over ubuntu desktop

THIS INSTALL MOSTLY WORKED, so very minor. Problem encountered was

- unclear error message from calamares (just error & close); the major issue I suspect; yet install worked booted & two OSes could be selected; mostly worked

I'll do some more installs of this type (unclean install) so this report could be marked as incomplete (waiting for me to get to that & see how severe etc)

-------

qa-test install to
- hp dc7700 (c2d-e6320, 8gb amd/ati rv610/radeon hd2400 pro/xt)
testcase: install using existing partition (sda6 or whatever I last used yesterday)

(two installs on box; lunar ubuntu-mate & mantic ubuntu-desktop; I'm selecting the ubuntu-desktop partition which has additional packages & music installed)

possibly of interest; ubuntu-desktop installed to two partitions being / & ESP; I only selected the / partition of lubuntu mantic & this install
