How do i resolve this issue E: Unable to correct problems, you have held broken packages. ? Does it depend on dpkg ? I'm not sure if /usr/***/dpkg file's been deleted ? Tried re-installing dpkg, but no success. I don't mind in re-trying all again

If it's depending upon dpkg, how do i un-install and re-install from fresh.

It seems problem is occurring because of presence of external repository.

1. First remove all the external repositories.
