This script works for 99% of use cases, I don't see an easy way through to make this work while keeping it as simple as it is for the normal OctoPrint user.
It needs to run as the user OctoPrint is installed as, pi
in your case so that it can access the installation, the plugins, make a backup and copy the stuff across to the new installation. It also needs to check that a few packages are installed. First it runs sudo apt update
, then some dpkg
commands that don't actually require root access to check if it needs to install additional packages. I guess the apt update could be switched and not run if not necessary, and you can just install python3-dev
and python3-venv
manually if this problem affects you.
I don't know of a way I can get people to run this script, run some things as one user and the rest as another user without running it as root. Running it as root then means I have to get people to provide the user they have installed OctoPrint as - this is harder than it sounds, as people try and run this script in OctoPrint's terminal for printer communication sometimes - most of them have no idea.
I won't be turning it on it's head and redesigning this script just to fit your use case - it sounds like you understand the process well enough to do it manually, so here's the 5 steps:
- Take a backup from within OctoPrint's backup/restore page. Can exclude everything possible.
- Move old virtualenv out of the way with
mv <path to old> <somewhere else
for safekeeping in case it goes wrong - Create a new one:
python3 -m venv <path>
- Install OctoPrint:
<path>/bin/pip install octoprint
- Restore the backup to automatically download the plugins.
