Twinkle 1.4.2-1_install error_Dependency not satisfiable ?

[Earl]

Hi,

I was stopped from installing Twinkle 1.4.2-1 by the error:

Error: Dependency is not satisfiable:  libasound2

Does this error come from the packaging or does it come
from something I have done wrong?

I checked and found
    libasound2    1.0.17a
    libasound2-dev    1.0.17a
    libasound2-plugins    1.0.17
have been installed previously.

Regards, Earl
