Dear all I tried to install Phenix on my virtual machine(Ubuntu) in win11. And got the following error message. ========================================================================== Phenix Installation version: 1.19.2-4158 machine type: intel-linux-2.6-x86_64 OS version: 5.11.0-40-generic destination: /usr/local/phenix-1.19.2-4158 # of processors: 1 ========================================================================= Configuring Phenix components...

I have root access to write to usr/local. And under /usr/local/phenix-1.19.2-4158 , I can see four folders:build, conda_base, doc, modules. Any one has suggestions? all the best Adam
