Hi,

I was able to download and install Lean on my Ubuntu. I followed all the steps in the readme.md to proceed with the installation. However, when I was running QuantConnect.Lean.Launcher.exe on backtesting-desktop mode I got the following error:

Does any of you have an idea of the reason behind this?

Thanks in advance for your help.
