Permission Error when uploading a file

[Jannik Theodor Heyderhoff]

Hello, it is me again hehe.

I was setting up my own Ibexfarm on one of my servers. I used an CentOs7 image for that purpose and installed everything according to this guide: https://adrummond.net/posts/ibexfarmdocker. It is Ibex 0.3.9  which I believe to be the latest version, right?

So the issue is that I cannot update my js files. When I try to upload an updated version of the same file I get an permission error.

I have no idea how I can change permissions on this docker because frankly I never used docker before using ibex. So what have I done wrong or what do I need to change?

Oh wait. I think you are not even supposed to change this but just add another file ....
