Hi, I have Houdini 20.5.487 py3.10 running on Ubuntu 22.04. I can't get it to open Houdini with any other user than root. I tried changing permission and ownership of the hfs dir but that didn't help. I should say, I'm new to Linux.

This is what I get in terminal

Thank you very much in advance!

Since you're new to Linux, could you elaborate a bit on how you attempted to change those permissions and how you verified them?

Thanks for the response

Sure, I wrote this

sudo chown -R $USER:$USER /opt/hfs20*

I did the same for sidefx directory then rebooted

When that didn't work I made a group and added my user

sudo chown -R root:houdini_users /opt/hfs20*

What is the output of your ls -ld /opt/hfs20*? This command will show your permissions. (use -lto check the contents of that folder)

Here's mine that works without issues:
If I'm not mistaken, the last r-xgrants anyone permission to read and execute.

I get this

Your original error logs mention SideFX Labs nodes a lot, could it be that the Labs package doesn't have read permissions? Just a blind guess.

nah, they have the same permission

Thank you Alex for your participation. I reinstalled Ubuntu and Houdini and now it works
