Can't uninstall FortiClient in Linux due to EMS and deregistration password

Hello

I'm facing a problem regarding uninstalling FortiClient to install a different version.


I'm on Linux (Kubuntu 19.10). When I try to uninstall FortiClient ( sudo apt-get purge forticlient or sudo apt-get remove forticlient ) I can't because "Unable to uninstall forticlient while connected to EMS". But when I try to disconnect from EMS ( sudo /opt/forticlient/epctrl -u ) it asks me for a "deregistration password". It's the same when I try to disconnect it from the GUI:

However, I don't have this password. I found a link about a "password recovery tool", but it is for Windows, and I don't have any program like that in the /opt/forticlient folder

https://docs.fortinet.com/document/forticlient/7.2.4/ems-administration-guide/543835/using-the-passw...

For what I remember, I installed my version of FortiClient from the company I formerly worked with (to access their VPN), so maybe it was a different version than the free one where I can have full control of the program.

Is there a way to get this password in Linux, or to force EMS deregisteration and/or uninstalling?

Thanks in advance

Hi @industrialWork46 

Since you are asking then I guess you don't have access to EMS or you can't contact EMS admin so he disconnects/deregister your FortiClient for you.

In that case I couldn't find an official method to fix your problem on Linux but you can still try the following:

  1. Stop FortiClient
  2. Double-check with ps -ef and kill any running FortiClient related process
  3. Rename /opt/forticlient/.fct_ec_registered. If you can't find the file in the mentioned folder try find it with find / -name .fct_ec_registered
  4. Run again sudo apt-get remove forticlient
  5. In case it doesn't work then boot your system in single user mode and try the procedure again
  6. In case the procedures fails roll-back the above change

Hope it helps.

It seems that your previous company has enforced via EMS "Require Password to Disconnect from EMS" and preventing "Allow User to Shutdown When Registered to EMS".

Can you try to remove this file "sudo rm /opt/forticlient/.fct_ec_registered" and than try to stop and uninstall FCT?

Disconnect Forticlient from EMS:

/opt/forticlient/epctrl -u

Uninstall FortiClient:
sudo apt-get remove forticlient
