Client 1.5 has Permission Problems on Ubuntu 24.04

[Bosper-the-Magician]

Hi!

Updated Core and Proxy today to Version 1.5 and tried new Client 1.5 on Ubuntu 24.04
After Activating Connection defguard-client just crashes.
Got this after some Tries:

zsh: IOT instruction  RUST_BACKTRACE=full defguard-client

Starting the client with sudo does work without a problem. But this was not needed before...
Any Ideas what causes this?

Thanks in advance

We are looking into possible issues with the Ubuntu package.

In the meantime a manual workaround for the permission issues is described here: https://docs.defguard.net/support-1/troubleshooting#unix-socket-permission-errors-when-desktop-client-attempts-to-connect-to-vpn-on-linux-machines

I can confrim. The Workaround works. Thanks for the quick help here
