I had this problem on Linux Mint.  TDE Control Center asks for the 
administrator password, which is of course the root password.  Ubuntu type 
distros don't have a root password.  Here is the solution I found: (It

a root password, and not for an administrator password.   It would make it 
more obvious what was wanted and what was the problem.
