Installing the BudgetDedicated Repository GPG Key
If you are adding the http://wine.budgetdedicated.com repository to your Ubuntu install you may be notified that it isn't verified. You can do this by downloading the GPG key for the repository and installing it with the commands shown below:
wget http://wine.budgetdedicated.com/apt/387EE263.gpg gpg --import 387EE263.gpg sudo apt-key add 387EE263.gpg
After this it should no-longer bother you about it not being secure. This will also let you know if anyone tries to spoof the server to install malicious software.
