The “GPG” (GNU Privacy Guard) is the distribution of “PGP” (Pretty Good privacy). The “GPG” key is used for security purposes, especially to encrypt data. Only the particular receiver can decrypt the files. To add the GPG key for envoy, execute the following command:
$ curl -sL 'https://deb.dl.getenvoy.io/public/gpg.8115BA8E629CC074.key' | sudo gpg --dearmor -o /usr/share/keyrings/getenvoy-keyring.gpg
Step 4: Authenticate the Key
Run the following command on the terminal to verify whether the key is signed. If the key is signed, the status will be “OK”:
$ echo a077cb587a1b622e03aa4bf2f3689de14658a9497a9af2c427bba5f4cc3c4723 /usr/share/keyrings/getenvoy-keyring.gpg | sha256sum --check
The output displays the “OK” status that means everything is settled properly.
Step 5: Add getenvoy Repository
After that, add the getenvoy repository to your system via the following command:
$ echo "deb [arch=amd64 signed-by=/usr/share/keyrings/getenvoy-keyring.gpg] https://deb.dl.getenvoy.io/public/deb/ubuntu $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/getenvoy.list
Step 6: Update the System packages
Again, update the system packages to adopt the new changes by issuing the following command:
$ sudo apt update
The current output represents the new packages added in Ubuntu 22.04
