Hi Stefan,

Which version of TDE do you have installed on your system?  Posting the
relevant /etc/apt/sources.list lines would help us know very quickly.

Around the time you mention the signing key was changed on the R14
repository, with the 3.5.13.2 repository being changed some weeks later. 
I have personally verified that the signatures on both the R14 and
3.5.13.2 PPAs are valid, so I'm wondering if you have an old line in
sources.list or sources.list.d. somewhere.

Thanks!

Tim
