Cant download OS

Hi there, so I tried to install Endeavour with a partition, however it seems to fail everytime with the error code: Boost.Phyton- fel I uppgift). This error code is in Swedish but ill try to translate it to English: Boost.Phyton- error in task.
Does anyone know what this means?

How did you create the live ISO?

That basically just means that something failed during one of the python modules.

In order to provide help, we need to see the entire log.
