Any help will be much appreciated.

It looks like you have one or more invalid scripts. Try removing the scripts from your scripts root temporarily and re-running the upgrade script.

Hello, Any help regarding this issue?

Hi,

Still the issue after deleting all files/scripts in the scripts folder.

This is just me spitballing and not based on your specific error, but I'd try disabling all plugins in configuration.py and also removing any reports if you make use of them.

[FGAGwendalG]

Hello,

I don't have any particular report or plugin.

Netbox has been installed and updated regularly since version 2. This is the first time I've had a problem like this, especially as the error doesn't allow me to find the exact cause.

I've just tried to upgrade to 3.5.3, same error:

I don't know much of the internals but it still looks like it finds something that it thinks is a script but is really not.

Can you show the outputs of these:

ls -l /opt/netbox-3.5.3/netbox/scripts
ls -l /opt/netbox/netbox/scripts

[FGAGwendalG]

The results of the commands are shown below:

As Jeremy said earlier:
