Ubuntu spotted at wild! 

Not quite so. But a colleague at office did recently ask me to take a look at her non-booting Ubuntu laptop (it was fsck problem). 

What caught my attention was she’s using 16.04 version. The last Ubuntu I used was 12.04, iirc? And it’s latest release apparently has reached the end of alphabet. Zesty Zapus. Maybe I should give it a try?  (Thank God for Virtual Machines. No need for total harddisk wipe-out like when I installed Ubuntu for the first time, 8.04).
