I just installed Linux Ubuntu 20.04.1 LTS in a virtual machine. I want to change my theme and my icons style. I downloaded Unity tweak tool for that purposes. The tool is in /usr/share/applications/Unity-tweak-tool.desktop, but I can't run it. in fact I cannot run any .desktop file, and when I right click on a .desktop file and then go to permissions menu, I am not able to check the Execute: ''Allow executing file as a file'' field, it says ''You are not the owner, so you can't change these permissions''.

I want to log in as a root user(owner) and I tried typing sudo -i and sudo -s in the terminal and provided my password, but it didn't work. How can I run .desktop files and is there a way to become an 'owner'??

You don't need to make a .desktop file executable. It is not executed anyway but rather read by the system which will run the application indicated on its Exec=... line.

In Ubuntu 20.04, Unity tweak tool was replaced with Gnome Tweaks. So /usr/share/applications/Unity-tweak-tool.desktop is obsolete and replaced with /usr/share/applications/org.gnome.tweaks.desktop.

Install it with sudo apt install gnome-tweaks.

Solutions to run it then:

  1. Press the Super/Windows key on your keyboard, which will open Gnome Dash. Then type tweaks and click on the Tweaks icon to run it.

  2. Run gnome-tweaks in a terminal (found in org.gnome.tweaks.desktop)

  3. In a terminal gtk-launch org.gnome.tweaks will launch the app through the .desktop file
