How about the message “WARNING: The following packages cannot be authenticated!” How can I install the key with 'apt-key'? And where is this key? If anybody this, please include this info here and then remove this question.

To remove that you need to add the key with apt-key add. An easy way to do this using gpg is as follows: gpg –recv-keys <keyid>;gpg –armor –export <keyid> | apt-key add -

Key =

wget http://deb.kamailio.org/kamailiodebkey.gpg apt-key add kamailiodebkey.gpg Hope that help Rory @GTWCMT
