Comment 15 for bug 1251193

Thank you Chris , Brian
I have tested it now , but unfortunately, it failed to upgrade due to dependency problem
please see the screenshot

I checked it up through

sudo aptitude -t trusty-proposed

and found one unsatisfied dependency package : libunity-core-6.0-9 ( =7.2.1+14.04.20140513-0ubuntu1)

please check it up and let me know what I should do
best regards for helping to solve this issue
