Recently I have seen many posts which are having problem with Dependencies as , if we got an error message
Depends: gvfs (= 1.6.1-0ubuntu1build1) but 1.12.1-0ubuntu1 is installed
Then we can solve the issue by
Code:
sudo apt-get install -f
But if we got something like
Depends: libgvfscommon0 (>= 1.1.7) but it is not installable
(focus on the Bold text) .Then apt-get install -f not going to solve this because of these errors

1 - Running dev versions and a package has not been updated to work with it's Dependants

2 - Running something from a PPA and they've not done everything.

So i am creating this thread which we can use for similar errors and to help users who are facing this issue .

Thank you Elfy for your Support.

So add your issue here and if possible the solution too .
Thank you all
