• GlobalProtect on Linux Ubuntu Debian
• GlobalProtect 5.2 and above when using CLI version.
• GlobalProtect 6.0 and above when using UI-CLI version.
• Ubuntu 20.04 Desktop & Server 

Workaround: 
The workaround for installing the GlobalProtect app on Ubuntu 20.04 is to use the dpkg utility instead of the apt-get utility.

CLI-Only:
The following command can be used to install the CLI-Only GlobalProtect Client 5.2.x or above:

$ sudo dpkg -i GlobalProtect_deb-5.3.3.0-3.deb

UI-CLI:
For the UI-CLI version supported from GlobalProtect 6.0 or above, you will need to install the libqt5webkit5 dependencies via apt-get, then install the GlobalProtect package with dpkg utility. 

$ sudo apt-get install libqt5webkit5
$ sudo dpkg -i GlobalProtect_UI_deb-6.0.0.1-44.deb

• If upgrading the Linux Ubuntu OS from 18.04 or 19.04 to 20.04, GlobalProtect should work as expected. 
• Upgrading from an older GlobalProtect 5.3.x version to the latest 5.3.x on Ubuntu 20.04 should work as expected.  
• Upgrading GlobalProtect from 5.3.x to 6.0.x should work as expected for CLI. If you wish to switch to UI-CLI version using GlobalProtect Linux 6.0 or above, you will need to uninstall the CLI-only version, then install the UI-CLI version. For uninstall please refer to the following document.
