No module named 'netbox.wsgi

[pompfe]

Did a clean install twice on Ubuntu 22.04. Used official install docs. And it always throws an error when I try to start the systemd services (4.). Development startup works (at the end of 3.), can access site and log in. Error is ModuleNotFoundError: No module named 'netbox.wsgi'.
What's wrong? Any idea? Thanks a lot!

Have you verified that netbox user has access to /opt/netbox/netbox/netbox/wsgi.py, including all the directories above it?

ls -ld /opt
ls -ld /opt/netbox
ls -ld /opt/netbox/netbox
ls -ld /opt/netbox/netbox/netbox

(you can enclose the outputs in three backticks: https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks)

[pompfe]

ls -ld /opt
drwxr-xr-x 3 root root 4096 May 3 10:15 /opt

ls -ld /opt/netbox
drwxr-xr-x 11 root root 4096 May 3 11:51 /opt/netbox

ls -ld /opt/netbox/netbox
drwxr-x--- 22 root root 4096 May 3 10:58 /opt/netbox/netbox

ls -ld /opt/netbox/netbox/netbox
drwxr-xr-x 15 root root 4096 May 3 10:44 /opt/netbox/netbox/netbox

YES, YES, YES - got it!
/opt/netbox/netbox got the wrong permissions. Changed them, and it works!
How could that happen? Did I do something wrong?

Thank you very much!

PS: And thanks for the three backticks.

Ah, and thank you for being extremely fast!
