This is probably a very simple issue, so sorry for bothering but I'm totally new to Ubuntu.
I have version Ubuntu 17.04.
My biggest issue is that when I click "install" after double-clicking the .deb file, it doesn't do anything. Literally, nothing - the text doesn't even change to "installing".
I tried opening it with dpkg like propesed here (as it appears to be similar to my case), but I keep getting dependency errors (it requires package dkms, but when downloaded dkms itself also gives me dependency errors, and at this point I feel that I'm just doing it the wrong way)).
Sadly, the USB device is currently my only option of connecting to the internet on this PC, so all the packages so far I've had to get by downloading on another device and dropping it off by USB.
sudo lshw -class network shows only my integrated (Ethernet port only) network adapter.
lsusb lists this:
Bus 002 Device 002: ID 2357:010e
Oh, and in case this is relevant - this installation was done with the "nomodeset xforcevesa" command, as I have gotten freezes during normal installation.
I hope that I didn't forget anything important, and thank you for help in advance.
