thx/Seasons Greetings Robie. For now, I don't know which way to turn except seeing months down the tubes 1. I acknowledge I'm the who lost a few very valuable work when a bug crashed my PC, which I can't fix whatever has caused my fluttering greyed out monitor screen, leading to crash after crash, saying for example mysql-server-5.6 5.6.27-0ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 2. I must set my ailing PC the side, save my files to my cloud; and when feasible wipe this new WD 1T HD clean, then I guess, install 15.04 in lieu of 15.10 3. Already, alternatively I bought a new laptop got me Win 8.1 obsessively wanting to auto-upgrade to Win 10full of advertisements. I mean, to get the peace of mind Linux brings, that I must partition that new laptop's HD and very carefully select and install an OS having better reports Again, Seasons Greetings!!!! ken On Mon, Dec 14, 2015 at 7:37 AM, Robie Basak
