Debian packages are published on Bintray repository. All packages are signed using the key 562CBC1C (fingerprint: 0CD5 AC59 DE5C 5A8E 0EE1 3849 3D99 BB18 562C BC1C):
echo 'deb https://dl.bintray.com/cert-bdf/debian any main' | sudo tee -a /etc/apt/sources.list.d/thehive-project.list
sudo apt-key adv --keyserver hkp://pgp.mit.edu --recv-key 562CBC1C
sudo apt-get update
sudo apt-get install cortex
If the command sudo apt-key adv --keyserver hkp://pgp.mit.edu --recv-key 562CBC1C
fails (because your infrastructure
refuses the acccess to pgp.mit.edu server key), you can run with the equivalent command: curl https://raw.githubusercontent.com/TheHive-Project/Cortex/master/PGP-PUBLIC-KEY | sudo apt-key add -
Once the package is installed, please configure Cortex.
