I accidentally uninstalled my active kernel as well as my graphics drivers using this command from a StackExchange suggestion:
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge After reinstalling the kernel, I am working on the graphics drivers.
ubuntu-drivers devices returns:

I am not experienced with packaging and do not want to mess something else up again, so I did not run it.
A side question: does anyone know how I can be certain that my kernel is running properly? I.e. that if I restart my computer it will boot?
uname -r returns:
4.15.0-43-generic
So I believe it is functioning. Is there anything else it would be smart to check?

nvidia-390 is part of the graphics-drivers PPA.
Run sudo /usr/bin/nvidia-uninstall to uninstall a manually installed driver, if you still got one.
Remove everything of your old NVIDIA driver (simulate first):
sudo apt remove --purge -s nvidia-* sudo apt remove --purge -s libnvidia-* If only nvidia packages are there to be removed, remove really:
sudo apt remove --purge nvidia-* sudo apt remove --purge libnvidia-* Run sudo apt update and ubuntu-drivers devices again.
If nvidia-390 is still recommended, add your output of sudo ubuntu-drivers autoinstall again.
