Upgrading from 3.4.4 to 3.7.8: Error upgrade command not found

[lp-hdd]

I am trying to get to version 4 eventually. I am not well versed in the Linux environment, just trying to upgrade our instance of NetBox.

Following the instructions on the upgrade page, everything checks out until I run the upgrade command:

sudo PYTHON=/usr/bin/python3.12 ./upgrade.sh

sudo: ./upgrade.sh: command not found 

The default version of python is 3.8, but I have installed 3.12 to run the upgrade.

I found this command to try and I get this:

PYTHON=/usr/bin/python3.12 /opt/netbox/upgrade.sh

I'm getting the same exact error trying to upgrade from 3.4.4 to 3.7.8.

I got it working running the upgrade command in the directory: /opt/netbox-3.7.8/

I was missing the extra python packages "python3-pip python3-venv python3-dev" so the upgrade script kept failing. I had to upgrade python from 3.9 to 3.12 and make sure I have the those extra packages for 3.12 and then the upgrade script worked.

sudo apt-get install python3.12-venv python3.12-dev <- same issue had to install the venv & dev packages I had only installed the python3.12 package
