Lack of command line feedback

[Donjan Rodic]

Rationale:
After upgrading from 12.10 to 13.04, my ~15 PPAs have been disabled. Reenabling them (they are automatically set to target 'raring') and launching udate-manager, it simply says "Failed to download repository information", "Check your internet connection.". There is no indication of what is going wrong, and the next intuitive idea (~$ gksudo update-manager) prints nothing while giving the same error popup.

A quick '~$ aptitude update' reveals that one of the PPAs simply doesn't have a 'raring' target.

Proposal:
update-manager should print it's current activities to stdout when invoked from the command line. Sure, one can/should implement error popups for every which possibility, but command line output is a fairly essential fallback.
