Workaround for installing FortiClient7.0 VPN on Ubuntu 24.04

On Ubuntu 24.04, installing FortiClient VPN v7.0 from a downloaded deb package errors due to unsatisfied dependencies:

sudo dpkg -i ./forticlient_vpn_7.0.9.0322_amd64.deb
Selecting previously unselected package forticlient.

dpkg: dependency problems prevent configuration of forticlient:
 forticlient depends on libgconf-2-4 (>> 0); however:
  Package libgconf-2-4 is not installed.

To clean up run: sudo apt --fix-broken install

This worked for me:

wget http://ftp.it.debian.org/debian/pool/main/g/gconf/libgconf-2-4_3.2.6-8_amd64.deb
wget http://ftp.it.debian.org/debian/pool/main/g/gconf/gconf2-common_3.2.6-8_all.deb
sudo dpkg -i ./libgconf-2-4_3.2.6-8_amd64.deb ./gconf2-common_3.2.6-8_all.deb
sudo apt install libnss3-tools
sudo dpkg -i ./forticlient_vpn_7.0.9.0322_amd64.deb
