"After this I gave $apt-get autoremove, a command usually used to remove
packages which have no dependancy with any other installed package."
I have packages that meet this criteria on my system but I want those
packages. So not having a dependency on another package isn't necessarily a
useful way to determine if the package in question is actually needed or not.
"Is it safe to remove these orphanaged packages?"
I would say that it depends on what those packages are for and if you want
the stuff that they do.
