Unclaimed Intel Network interface -Ubuntu 18.04 Kernel:5.4.0-87-generic

Question

hi everyone, it's my first time in the forum. My problem is with the ethernet network interface. It is UNCLAIMED. This is the result of the lshw -class network command:

WARNING: you should run this program as super-user.

Quindi l'unica soluzione è passare a Ubuntu 20 ?

che 18.04.xx hai?
cosa vedi da: modinfo e1000e
alternative a aggiornare:

compilare il modulo e1000e

compilare il kernel

(10 Oct '21, 08:33) sacarde

brutte notizie...

ho scaricato l'ultimo driver per la e1000e 3.8.4

https://www.intel.com/content/www/us/en/download/14611/15817/intel-network-adapter-driver-for-pcie-intel-gigabit-ethernet-network-connections-under-linux.html

compilato e creato il modulo, ma da: modinfo e1000e non risulta alcun device:

8086:3101

(10 Oct '21, 10:06) sacarde

da qui sembra che esista col nome "igc"

https://linux-hardware.org/index.php?id=pci:8086-3101-8086-0000

che vedi da: modinfo igc

Grazie mille per avermi seguito. La mia versione di Ubuntu è la 18.04.6 L'output di modinfo igc è:

Ora siccome non sono mai andato cosi in profondità con linux ti chiedo posso installare un kernel superiore alla 5.4 su Ubuntu 18? e quindi è questa la strada ? prima di fare danni piu che altro. Grazie mille ancora
