Fixing the “can’t find keyring debian-archive-keyring.gpg” Error

When the package manager on a Debian-based system, such as APT, is unable to locate the GPG keyring file linked with the Debian archive, the error “can’t find keyring debian-archive-keyring.gpg” usually appears. The keyring file holds the cryptographic keys used to check if Debian repository downloads are safe. The file “Debian-archive-keyring.gpg” is the GPG keyring linked to the Debian archive.

Some of the reasons behind the error include:

1. It’s possible that the keyring file is not set up on the system or is missing.

2. It’s also possible that the file is corrupt and that’s why the package manager can’t use it.

3. Package handling may be looking for the keyring file in the wrong place because of an error in the APT settings.

Solutions

1. Run the next command to refresh the package listings. Getting the most recent keyring file can fix the issue.

2. We can try a new setup of the debian-archive-keyring package in case the keyring file is absent or damaged.

3. Make sure the keyring file is in the right place. /usr/share/keyrings/debian-archive-keyring.gpg is typically the default path.

4. Verify that the person using the package manager has the right to access the keyring file. Use chmod to change the rights if needed.
