Hey,
I am obligated to use Forticlient VPN for my workplace. Unfortunately, whenever I try to open the Forticlient GUI, I get a completely blank screen. The navigation menu on the top loads fine, I can press file which gives me an option to quit the application (and nothing else), and I can press Help which gives me two links to documentation that don't help me in this situation. The program itself doesn't load however.
Does anyone have an idea how to solve this issue? I just tried to install the rpm-package from the VPN-only client. I guess it may be specifically designed for CentOS only? If so, is there any way to get it working on Fedora?
My terminal output doesn't give me a lot:
[sjoerd@lennart ~]$ forticlient
Fontconfig warning: "/usr/share/fontconfig/conf.avail/05-reset-dirs-sample.conf", line 6: unknown element "reset-dirs"
Platform detected: fedora
[ '/usr/lib/opt/forticlient/gui/FortiClient-linux-x64/FortiClient' ]
did-finish-load
window-all-closed
I'm running Fedora Silverblue with the latest base image from the 3th of June 2022 if that helps anyone.
Kind regards,
Sjoerd

as far as I read now that is not a problem with forticlient but more some bug in the fontconfig package shipped with fedora.
There is entries in their bugtracker: https://bugzilla.redhat.com/show_bug.cgi?id=1770450
I did not yet find a workaround except from (prolly manually) update fontconfig.
At least that's the only warning or errror that is shown in your quote.
CentOS/Fedora/Redhat should be compatible though...

Thank you for the reply, that gives me at least a hint of where to look for a further solution. I will report back if I manage to fix it by fiddling with fontconfig!
the fontconfig message thus is just a warning. So it might not be the actual reason...
You could try to execute 'strace forticlient' to see what it does and opens etc.
(you might first have to install strace).
the strace will give you a load of information so you will have to have a closer look...

Check that fortivpn service is running and directory /var/lib/forticlient exists
So I just reinstalled Forticlient to check this, and bingo... this directory does not exist at all. Not sure if it should, it still exists in /var/opt/forticlient. But nothing in /var/lib. I'm pretty sure the main issue has something to do with the immutable nature of Silverblue, since it works fine on Workstation.
Maybe I'll check if Fortinet has some feedback/issue tracker for general development just to notify them that this issue exists. But otherwise I think it's a bit of a dead end at the moment.
Tested on FC32, FC35, FC36 and FC37. - Seeing the same, and some observations in differences between deb and rpm is that '/usr/bin/forticlient -> /opt/forticlient/forticlient-cli' is lacking on Fedora. Maybe /opt/forticlient/fortivpn is the same as forticlient-cli on Ubuntu/Debian.
If I start 'FortiClient gui' manually
$ /opt/forticlient/gui/FortiClient-linux-x64/FortiClient gui

22:40:00.616 › Platform detected: fedora

and then I get a white blank screen.
How about doing some simple QC before shipping your software? Any suggestions are appreciated.

I want to decommission the Aruba VPN controller, but as long as the forticlient isn't on par with the Aruba VIA VPN client on all platforms (Android, IOS, MacOSX, Linux (deb/rpm) and Windows), that's not happening.
Thanks!
It's very interesting that it's not working for you though, as I think our underlying issues are different in nature (unless your GNOME machine is Silverblue as well).
Overall poor QC when shipping software is a thing I notice more often, and I sometimes seriously doubt if they ever tested their software even once on anything else than their own dev system. Not just with Linux applications, but in general. I've got popular (>1M downloads) apps on my iPhone that are so painstakingly broken, even though iOS is like the most predictable system out there (barely any hardware variance, almost all people use the latest version). It's honestly baffling sometimes.
Some progress. forticlient-7.0.8.0292.1.el7 finally works on FC37 with the latest updates and Mate 1.26.1 window manager.
On my main machine with Gnome 43.3, it still does not.
To comment on this, as I see I never reported back on this (to be fair, I said I'd report back if I'd manage to set things up, I didn't).
I found Forticlient works "fine" for me on Fedora 37 Workstation (both on GNOME as DE, and I also tried on the KDE spin in a virtual machine). I run Fedora Silverblue on my personal laptop however, and it is there it is having these issues.
So it is compatible enough with Fedora itself. However, it has difficulties with the immutable filesystem from Fedora Silverblue. It's been a while since I've looked into this in detail, but I think vovan might be on to something and it might have issues with creating a valid folder in /var/forticlient.
Unfortunately this is not something I've been able to resolve, other than using a VM for my forticlient VPN needs, and it may need some fundemental changes to the client's code to fix this (just guessing) while only a very small subset of the overall market uses immutable Linux distro's. Personally I believe it's the future, so maybe at one point it will be properly supported, but as of right now (March 2023) I don't think it's possible to run Forticlient on Fedora Silverblue.
