5. Add the generalbytes repository to APT

For installation and updates, the repository must be specifically added to the Ubuntu system.

Create the repository file:

Code Block
sudo touch /etc/apt/sources.list.d/generalbytes-repo.list

Edit the new file using nano:

Code Block
sudo nano /etc/apt/sources.list.d/generalbytes-repo.list


Add the following line to the file:

Code Block
deb [arch=amd64 signed-by=/usr/share/keyrings/generalbytes-repo.public] ./stable main
  • Replace “LICENSE” with your actual GENERAL BYTES approved license key.



  • Save and exit the nano editor (Press Ctrl+X, and answer “Y” when asked to save the file).

If you prefer to do it in a single line, use this script:

Code Block
read -p"Enter your license number and press ENTER:" LL && [ "$LL" == "" ] && echo "bad lincence number try again" || sudo sh -c  "echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/generalbytes-repo.public]$LL ./stable main' > /etc/apt/sources.list.d/generalbytes-repo.list"

6. Update the Ubuntu system repository.

Code Block
sudo apt update



The license issued by GENERAL BYTES may be revoked without warning.
