Hi TL, I use the below which may help: wget -O- https://deb.kamailio.org/kamailiodebkey.gpg | sudo tee /etc/apt/trusted.gpg.d/kamailio.asc This adds the key but not via apt-key, then just add your repo to sources.list.d like previously.

Hello, There is actually a new more-preferred way of doing this. It is slightly more work, but it directly connects the GPG key to the repository with which it is being used. 1. Download the key and de-armor it (i.e. convert from ASCII to binary): ``` wget -O- https://deb.kamailio.org/kamailiodebkey.gpg | gpg --dearmor | sudo tee /etc/apt/keyrings/kamailio.gpg ``` 2. When adding the repository, tell apt that this is the key that should be used for it: ``` deb [signed-by=/etc/apt/keyrings/kamailio.gpg] http://deb.kamailio.org/kamailio57 CODE_NAME main ``` This has actually been supported for many years, but it is becoming a lot more common now because it prevents a stolen key from one repository from being used to sign fake packages in another repository.
