To keep this concise, I am having the exact same issue described in this question: Neither Ethernet nor WiFi adapter working on Lenovo Thinkpad P14s under Ubuntu 2x.04
I would've left a comment on there to ask a further question, but I am very new to the community, so I don't have enough reputation points :\
The solution given in that question appears to be elegant and functional according to the poster's comments, but I am lost as to performing this step without internet access on my machine.
The desired command: sudo apt install linux-oem-20.04d
I've spent about 6 hours trying ways to get the package onto my machine. The primary method I've attempted is installing ubuntu in a VM on a different machine (with wifi), executing sudo apt -d build-dep linux-oem-20.04d, and then copying the .deb files onto a usb to transfer onto my ThinkPad and run sudo dpkg -i *.deb
This method was found here: https://stackoverflow.com/questions/16919114/run-sudo-apt-get-install-without-internet-connection
My questions:
Is this method correct? I've been running into lots of issues copying the files onto my usb, so I was thinking next step would be to install a partition of ubuntu on my other machine instead of doing it in a vm. I am just hesitant of going forward with this in case it is pointless.
What other ways could this be accomplished? Everything I've found involves some raw transfer of those .deb files, so I'm wondering if there is some other step that would be better.
