failed installing libappindicator:

dpkg: error processing archive libappindicator1_0.4.92-8_amd64.deb (--install):

@Ellatorg to solve the problem visit the following page and download another libappindicator1 version. (http://ftp.de.debian.org/debian/pool/main/liba/libappindicator/)

The following works for me:
http://ftp.de.debian.org/debian/pool/main/liba/libappindicator/libappindicator1_0.4.92-7_amd64.deb

No such file or directoryrchive 'forticlient_vpn_7.0.0.0018_amd64.deb

@mvc1009 it also work for me, thank!
My OS: Linux 5.14.0-kali4-amd64 #1 SMP Debian 5.14.16-1kali1 (2021-11-05) x86_64 GNU/Linux

Change the firt line with this:
curl -p --insecure "http://ftp.de.debian.org/debian/pool/main/liba/libappindicator/libappindicator1_0.4.92-3.1_amd64.deb" --output libappindicator1_0.4.92-8_amd64.deb

cause the link is not found so the package is not downloaded but it save the output anyway

I got it working with a different order (also added @carlosmaroot line):

sudo apt-get install libdbusmenu-gtk4
sudo apt-get install libgconf-2-4

curl -p --insecure "http://ftp.br.debian.org/debian/pool/main/libi/libindicator/libindicator7_0.5.0-4_amd64.deb" --output libindicator7_0.5.0-4_amd64.deb
sudo dpkg -i libindicator7_0.5.0-4_amd64.deb

curl -p --insecure "http://ftp.de.debian.org/debian/pool/main/liba/libappindicator/libappindicator1_0.4.92-3.1_amd64.deb" --output libappindicator1_0.4.92-8_amd64.deb
sudo dpkg -i libappindicator1_0.4.92-8_amd64.deb

wget https://filestore.fortinet.com/forticlient/downloads/forticlient_vpn_7.0.0.0018_amd64.deb
sudo dpkg -i forticlient_vpn_7.0.0.0018_amd64.deb

EDIT: when installing forticlient, I've encountered issues with DNS: apparently, one of the dependencies of forticlient (network-manager-fortisslvpn) erases your DHCP config and essentially eliminates all of your nameservers under /etc/resolv.conf, so you might wanna check this out: https://www.tecmint.com/set-permanent-dns-nameservers-in-ubuntu-debian/.

@JulianGR Thanks So Much!!

Works good for me, but previously need to remove previous libappindicator1 pkg

Love it. This works for me really good! Download forticlient.deb from the browser.
