Debian Intel Microcode Paket installieren

Infos/Status prüfen:

grep -E 'family|model|stepping|microcode' /proc/cpuinfo | head -5

dmesg | grep -i microcode

In /etc/apt/sources.list muss zusätzlich die Paketquelle non-free-firmware aktiviert werden – Beispiel:

deb http://deb.debian.org/debian/ bookworm main non-free-firmware
deb-src http://deb.debian.org/debian/ bookworm main non-free-firmware

deb http://deb.debian.org/debian/ bookworm-updates main non-free-firmware
deb-src http://deb.debian.org/debian/ bookworm-updates main non-free-firmware

deb http://security.debian.org/debian-security bookworm-security main non-free-firmware
deb-src http://security.debian.org/debian-security bookworm-security main non-free-firmware

Dann:

apt install intel-microcode

Und die Kiste neustarten.
