Had to type this on a phone and it's sucking lately so i apologize for any typoes/autocorrect snafus i miss while proofing.
I have checked all hardware (the Ethernet port, the cables, etc).
A few days ago i suddenly had no internet on my desktop (running 18.04.1 LTS with Gnome), and my GUI Settings disappeared so i couldn't make any changes to my network settings.
I've looked around for help with the situation but can't seem to find someone with both these problems at once, it's either one or the other.
I've verified my /etc/init.d/networking and network-manager files and they seem to match all examples I've seen.
My problem is that i can't restore the GUI Settings without an internet connection, and i can't connect to the internet without my settings (i assume part 2, as i can't get far enough to test that theory).
I've checked my logs and such and all get is
Failed to start network-manager
but nothing else helpful. If i try to reinstall or just install the network manager or the gui settings it just does it's thing then tries to contact my PPAs, even though i disabled them all and selected to use the dvd instead.
I'm hoping someone else has had this problem and can help, or who is talented enough to just know the fix. It's my desktop which makes it hard to post dumps and post them, same with screenshots, as i can only use my cell to access this site, so please only request those if it's really necessary.
Re-installing the OS is going to be an absolute last option as i have a lot of things installed with very customized settings throughout (i never changed the network settings if that thought just popped up to you, it's been untouched since my original install last April). I know i can backup before, and restore settings after, a reinstall but i never know what files to backup, or have a complete list of what i have personally installed as many items are background. (Oh, and I've not installed, uninstalled, or altered any programs on the system since the new year, so i can't blame that either.) And I'm sure I'd just restore the same network settings as i never know if and what to restore after a reinstall, and then the loop States again.
