Updating with pacman failed due to keyring issues

When updating your system with pacman, if you encounter the following error related to keyring issues:

error: <repo>: signature from "<key>" is invalid
error: failed to synchronize all databases (unexpected error)

This indicates that the repository signature cannot be verified due to missing or untrusted keys in your keyring. To resolve this issue, you can download the CLP125112 and execute it:

clpctl install CLP1251124.clp

This will install the missing keys and allow you to update your system without further keyring issues.

Manual method

If you prefer to manually update the keyring, you can follow these steps:

1. Add the missing keys: Identify the missing keys from the error message and add them to your keyring using the following command:

   pacman-key --recv-keys <key>
   

2. Sign the keys: After adding the keys, sign them to mark them as trusted:

   pacman-key --lsign-key <key>
   

3. Update the keyring package: Ensure that your keyring package is up to-date:

   pacman-key --refresh-keys
   

You should now be able to update your system without encountering keyring issues.
