Comment 14 for bug 1864787

dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)
testcase: BIOS, internet, no encryption, re-use /home thus manual partitioning

I forgot the `sudo -E calamares -d` to cause calamares to get extra debug info, so re-run
boot 'live' system & use KDE partition manager to erase sda9 (prior / which is listed as unknown), apply, then format is ext4 so sda9 again.
deactivate swap then exit KDE partition manager.
open term to use command to run calamares using `sudo -E calamares -d`
Summary - manual partitioning, cause format of sda9 (ext4) for '/" & no-format for sda8 or /home

lubuntu@lubuntu:~$ sudo -E calamares -d

this is session.log from requested command
