If you encounter issues with GPG keys while managing packages on AlmaLinux, it’s essential to ensure that your system recognizes and trusts the appropriate keys. This tutorial will guide you through the process of checking for and importing the necessary GPG keys to avoid disruptions in receiving updates.

Step 1: Check If the New GPG Key is Already Trusted

  1. Open your terminal. You can access your terminal through your system’s application launcher.
  2. Run the following command to query the RPM database for the new GPG key:
   rpm -q gpg-pubkey-ced7258b-6525146f
  1. Interpret the output:
  • If the output shows gpg-pubkey-ced7258b-6525146f, your system already trusts the new GPG key, and no further action is required.
  • If you receive an error stating package gpg-pubkey-ced7258b-6525146f is not installed, you’ll need to import the key.

Step 2: Import the New AlmaLinux 8 GPG Key

If the key is not already trusted, you can import it using one of the following methods:

Method A: Importing from the Web

  1. Import the key directly from AlmaLinux’s repository:
   rpm --import https://repo.almalinux.org/almalinux/RPM-GPG-KEY-AlmaLinux

This command will add the new GPG key to your RPM database. If the key is already present, it won’t make any changes.

Method B: Importing from a Local File

This method is useful if your device is in an air-gapped environment or does not have an external network connection.

  1. Ensure that you have at least almalinux-release package version 8.8-3.el8 installed:
    You can check your version of almalinux-release by executing:
   rpm -q almalinux-release
  1. Import the key from the local file system:
   rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-AlmaLinux

Step 3: Verify the Import

After importing the GPG key, it’s good practice to verify that the key is now recognized by your system.

  1. Run the query command again to check if the system trusts the new key:
   rpm -q gpg-pubkey-ced7258b-6525146f

If the key is correctly imported, you should now see the key ID as the output.

Conclusion

By following these steps, you can ensure that your AlmaLinux system correctly recognizes and trusts the necessary GPG keys for secure package management. Regularly updating your system and ensuring the almalinux-release package is up-to-date are good practices to avoid such issues in the future.
