Does someone know a proper way to install Okular on Linux Mint? I used command-line and package manager, both give same result: Okular doesn't have any icon, cannot open pdf, interface has disabled all functions and it turns off when you press it.
Usually you would run:
sudo apt-get update
sudo apt-get install okular
That should do it. If you having problems beyond that then you can try
sudo apt-get install oxygen-icon-theme*
After that it's off to google.
