How to let forticlient vpn work properly in Ubuntu 24.04?

I installed FortiClient VPN 7.4.3.1736 (forticlient_vpn_7.4.3.1736_amd64.deb) on Ubuntu 24.04 using the package downloaded from the official Fortinet website.

The VPN itself appears to work correctly and I can successfully connect to my VPN gateway.

However, every time I start FortiClient VPN, I always receive one or more popup messages reporting conflicts or errors related to NetworkManager. The popup then asks whether I would like to upload the error report.

Although the VPN is functional, these error popups appear every time the application starts, which suggests there may be a compatibility issue or a missing component.

I have already tried several troubleshooting steps suggested by ChatGPT, but none of them resolved the problem.

I was also told that FortiClient VPN 7.4.4 or 7.4.5 might contain fixes for Ubuntu 24.04, but I cannot find these versions on the Fortinet download site.

Could anyone please advise:

- Is this a known issue with FortiClient VPN 7.4.3 on Ubuntu 24.04?
- Are FortiClient VPN 7.4.4 or 7.4.5 available for Linux?
- Has anyone else experienced these NetworkManager-related popups, and if so, how did you resolve them?

I don't know from where you downloaded it, but try to go with the repository. I think that apt repo should give you the later versions. I don't recall having issues with the network manager as described with any FortiClient version. I would make a guess that FortiClient is supposedly wanting to handle an interface that the nm has its hand over.

Many thanks. I followed the suggestion and added the Fortinet apt repository.

The repository currently provides forticlient 7.4.7.1868. After upgrading from the standalone VPN package (7.4.3.1736), I noticed that the Ubuntu 24.04 error popups no longer appear.

Previously, I would regularly see dialogs such as:

"Sorry, Ubuntu 24.04 has experienced an internal error" with ExecutablePath: /usr/sbin/NetworkManager
"Sorry, Ubuntu 24.04 has experienced an internal error" with ExecutablePath: /opt/forticlient/fortitray

After installing 7.4.7.1868 from the repository, I have not seen either of these popups so far.

However, I ran into a different issue. The repository package appears to behave as the Zero Trust Fabric Agent rather than the standalone VPN client I was previously using. The GUI only shows the Zero Trust Telemetry page, and the VPN CLI reports:

"FortiClient VPN is unavailable: FortiClient VPN trial has expired. Please contact your administrator or connect to EMS for license activation."

If I only need SSL-VPN connectivity, is there a way to use the VPN module without EMS registration or license activation, similar to the standalone FortiClient VPN package?

Thanks for the feedback. I suppose the network manager and FortiClient were indeed not working well together.

I think that version in the repository isn’t the standalone VPN but fully licensed and as such wants to be licensed. Your previous standalone version, do you have an option there to download a 7.2 variant?

Thanks for your quick reply.

Yes, I have forticlient_vpn_7.2.2.0753_amd64.deb, which works well with Ubuntu 20.04. However, since Ubuntu 20.04 is quite old, I need to migrate to Ubuntu 24.04.

I tried installing forticlient_vpn_7.2.2.0753_amd64.deb on Ubuntu 24.04, but it was unsuccessful. Therefore, I had to install forticlient_vpn_7.4.3.1736_amd64.deb instead.!--scriptorendfragment-->

FCT 7.2.2 doesnt have support for Ubuntu 24.04 , this starts with 7.2.6

if you have an account on the support portal and a product registered w/ valid support you can download the required version from there
