This command will trigger a job named 'Device-certificate-fetch'. A primary cause of this error is Palo Alto Networks Bug ID

A primary cause of this error is Palo Alto Networks Bug ID . This software defect causes the firewall to generate temporary .pub_pem files in the /opt/pancfg/mgmt/ssl/private/ directory each time the show device-certificate status CLI command is executed. Due to a flaw, these files are not deleted afterward. Over time, especially on firewalls with frequent status checks, this directory can become 100% full. Once the disk partition is full, the firewall is unable to write new data, leading to a failure to fetch or update the device certificate and triggering the public key mismatch error. This is a critical bug that has been fixed in specific PAN-OS releases (see the "Resolution" section below). Over time, especially on firewalls with frequent status
