So, it looks the problem is about this error:
/usr/share/doc/libglib2.0-0/changelog.Debian.gz' is different from the
same file on the system
//I also tried following , end up with same
sudo apt-add-repository "deb http://archive.canonical.com/ $(lsb_release
-sc) partner"
sudo apt-get update && sudo apt-get install skype
I'm feeling confusing to troubleshoot this kind of installation issue,
anyone run into the same issues and any workaround?
