The signing component for the Linux operating system is available as a .deb program file, and is available at:

vep-podpis_1.0.17.0.deb

or for Ubuntu 22+:  vep-podpis_ubuntu22.deb

You can open and install the file using the default program installer.

Save the option file and install it in the terminal with the command:

sudo dpkg -i vep-podpis_1.0.17.0.deb 
or
sudo dpkg -i vep-podpis_ubuntu22.deb 

When entering the VEP portal, you will need to allow the signing component to run in the browser.

To remove a signature component, use the command:

sudo dpkg -r vep-signature
sudo dpkg --purge vep-podpis
