Install firmware-atheros package to get rid of the firmware errors. The x509 stuff is a known thing with older Acers. If you have secure boot enabled, you can turn it off to see if it goes away, it's harmless otherwise.
- it seems i have firmware-atheros installed, and i have secure boot disabled. So if it's harmless, is there a way to hide those messages. Thanks for answering
