Importing Debian repository GPG key

Packages at http://www.kiberpipa.org/~tomaz/tablix/repo are signed with GPG. Since the key used for this repository is not included by default in apt's keyring you have to add it manually if you would like to authenticate the packages.

Here is the fingerprint of the GPG key used:

F2FC FD4C D2CC 1287 E03B  906D 7824 CDE4 6515 74D4

To add this key to the list of keys trusted by your apt follow these steps:

First import the key from a GPG server:

gpg --keyserver hkp://wwwkeys.eu.pgp.net --recv-keys 651574D4

Then add it to the apt's keyring:

gpg --armor --export 651574D4 | sudo apt-key add -
