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.
Debian operating system
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
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
@Romario35 the pcie port error of this agent message is likely a kernel bug and from what research I've done all forums have stated it can be safely ignored.
The other errors are Certificate and firmware related.
Probably a cert that needs updated in order to access the firmware? Complete guess there but the error sites a wiki page to research.
