no public key

[angel yung]

Hello eveyone,

I have a problem with my update from sid, I kept on getting this message

W: There are no public key available for the following key IDs:
010908312D230C5F
W: You may want to run apt-get update to correct these problems

I ran apt-get update again and same error appears. Does anyone know how to get rid of this warning message?

Thanks a lot in advance.
