I upgraded to Ubuntu 20.04 yesterday from 19.10. Now, I can't access any .desktop files. The icons are no longer showing in /usr/share/applications nor on the desktop. They show as executable icons instead, which usually means it doesn't trust the file, which is normal if you haven't used the .desktop file before.
Strangely enough, double-clicking the icons does nothing. I don't get a prompting to allow it. Everything on the dash (items in my favorites) loads with the right icon and in the right place, and ctrl+alt+t still opens the terminal. For now, I've been using the terminal to open programs like Zoom and WPS Office. As long as I know the command to open the program, I can launch it in the terminal. Also, I think the system uninstalled Steam because Settings doesn't find it in the list of applications and steam won't work in the terminal.
我应该将系统回滚到18.04吗？
