There is support method given for installation of debian and rpm package manager. There is tgz file also. I extracted the tgz file and ran install.sh file. This gave below output.
$ sudo bash install.sh
Password:
systemd is detected.
Enable gp service...
Create symlink for gp cli...
Starting gp service...
Enable gpa autostart...
Starting gpa...
but after starting command "globalprotect" it gave below error.
$ globalprotect
Cannot connect to local gpd service.
There is are below list of files in same directory as install.sh
$ ls -t
release gpd gpshow.sh install.sh pangps.xml pre_exec_gps.sh
globalprotect.1.gz gpd.service gp_support.sh Makefile PanMSInit.sh uninstall.sh
I installed global protect from this link.
