Blank GUI screen for Forticlient 7.0.7 VPN on Ubuntu 16, 18, and 20

[Serguei]

Hi am now very tired of it of multiple fresh installs in Ubuntu 15.04, 18.04, and 20.04...

(First I was trying with a CLI options only, getting a bogus "license expired message".)

Then with GUI I am not getting anything but the Window pop up and no elements

on it; it's just blank.

This is with the latest 7.0.7 FortiClient forticlient_7.0.7.0246_amd64.deb from either the official repo using this procedure:

https://www.fortinet.com/support/product-downloads/linux

or downloading a VPN only deb file forticlient_vpn_7.0.7.0246_amd64.deb manually from

https://www.fortinet.com/support/product-downloads#vpn (https://links.fortinet.com/forticlient/deb/vpnagent)

Gets stuck in this:

Starting FortiTray 1
23:25:41.945 › Starting FortiTray
Platform detected: ubuntu 1
23:25:41.949 › Platform detected: ubuntu
[ '/opt/forticlient/gui/FortiClient-linux-x64/FortiClient' ] 1
23:25:41.951 › [ '/opt/forticlient/gui/FortiClient-linux-x64/FortiClient' ]
Saml - init 1
23:25:41.975 › Saml - init
did-finish-load 1
23:25:42.409 › did-finish-load
ready-to-show 1
23:25:42.411 › ready-to-show

and it only shows the blank window and hangs in there.

Both result in the same behavior. What am I doing wrong?

Hello Serguei,

I found this old discussion:

https://community.fortinet.com/t5/Support-Forum/Forticlient-blank-screen-Ubuntu-18-04/m-p/42386

Does it help?

Hello Anthony

Is it suggested to use openfortivpn cli, but in my case it's not applicable as I need to use OTP and openforti does not support SASL.

I have the same problem with blank scree in FortiClient app on linux. 

Is it possible to fix it?

Hello everyone, I found the solution to this problem, you need to have 

/opt/forticlient/fctsched

Running in the background. If you have systemd, check that forticlient service is up and running:

# systemctl status forticlient.service

Also check that directory exists:

/var/lib/forticlient

Hi, I have Ubuntu 22.04.3 and I am having the same issue even when the service is up and running. I checked that the directory /var/lib/forticlient exists.
