I have tried apt-get autoremove, that gives similar error. Apt-get -f install gives the above and even apt-get install samba-common won't install....I tried installing each package one at a time and still have the issue.

This happens on both pi1 installs, so not isolated to one pi (one pi has 6 upgrade packages and the other 10 upgrade packages).

Can anyone tell me how to fix this please?
