Upgrade Ubuntu 20.04 to 22.04 with Inventree?

[StormTrooper]

I've got Ubuntu 20.04 running with Inventree 1.1.11 and trying to upgrade to 22.04 due to 20.04 being EOL.

Have cloned my prod server and ran a test upgrade. The OS upgraded fine however Inventree is not happy.

In the journalctl I see this:

Feb 15 10:36:39 inventree-clone inventree-web-1.service[826]: /opt/inventree/vendor/pkgr/processes/web: 2: exec: env/bin/gunicorn: not found

I tried to run a update and things get even worse

inventree@inventree-clone:/opt/inventree$ source env/bin/activate
(env) inventree@inventree-clone:/opt/inventree$ invoke update
-bash: /opt/inventree/env/bin/invoke: /opt/inventree/env/bin/python3.9: bad interpreter: No such file or directory

Looks like as part of the upgrade python was upgraded to Python 3.10.12

Any ideas on how to get this solved?

Can you try fetching the install/upgrade logs? Something in upgrading the InvenTree package must have gone wrong.

In general a installer / deployment or general bug report would be a better format for questions like this as we now will probably go to the questions asked there but less efficient

Thanks, I've raised a bug report and added the OS upgrade logs.
