I used synaptic and tried to fix and I get this error E: Could not perform immediate configuration on 'libc6'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)
When I select for removal I get
Removing this package may render the system unusable.
Are you sure you want to do that?
