While I mostly agree with what you say, the thing is Django was probably asked what was the best way to ship the laptop, but he probably just didn't know :

- he is from neighboring DRC, not Ugandan;

- based on his description of his travels, he lives in the overwhelmed Kyaka II camp, and was probably recently displaced due to the M23 campaign;

- he was probably already enrolled in the course before being displaced, so a young full-time student, probably not even aware of how the system work in his origin country.

My bet is that he just said to ship it to a drop location in Kampala and that he would find a way to get there to retrieve it.

In the end, the Hubris was probably not on OP's side, but on Django's side, thinking he could get a laptop shipped to him while avoiding entirely the camp's organization. Although he did manage it after all...

It sounds less like arrogance and more like both sides trying to improvise with incomplete information

Well, it was more for the overconfidence meaning than the arrogance one.
