#195782 — How to rebuild the keys for APT.

I recently had to move a disk image from machine to another machine 
however when I fired it up on the new machine the APT keys were 
broken/corrupted. The errors I'm getting are below... Is there a simple 
way of fixing this?

perhaps it is not only the gpg keys that got broken. How did you make/move
the disk image to another machine?

there is a page on the Debian Wiki how you import the keys, but it might be
something else missing as well

SOLUTION:
I went though and added all the keys again and now it's working again.

sudo apt-key adv --keyserver keyserver.debian.org --recv-keys [KEY_MISSING]

Works good now.  Thanks everyone for the help.
