Sometimes you need to make a fresh Ubuntu install.
For some apps, just download and install. My of apps:
Chrome
Mendeley
Dropbox
Anaconda
Inkscape
GIMP
Texmaker
For the harder ones, you need some commands to issue after reinstalling.
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt update
$ sudo apt upgrade
$ ubuntu-drivers devices
$ sudo ubuntu-drivers autoinstall
$ nvidia-smi
