ATLAS Experiment OpenData – User Notes

This is just a quick note for people using ATLAS Experiment OpenData with Oracle VirtualBox VMs on Fedora.
The installation of the ATLAS VM is wonderfully described here. I just have two quick notes. One for users that run Oracle VirtualBox on Fedora (31) and one that is for the VM itself.

First, you’ll need to install the VirtualBox Extension Pack to be able to start the VM. This is because it needs USB 2.0 support enabled to be able to start the VM. Setting USB settings to USB 1.1 will not fix this. The VM will start, but will get stuck during boot up.
On Ubuntu, the VirtualBox Extension Pack is provided as an Ubuntu package and can be installed with the command

sudo apt install virtualbox-ext-pack

On Fedora there is no such package. So you’ll have to get the VirtualBox Extension Pack from the Website so you’ll have to get it from the above link and manually install it. This is quite easy, though.

Click the download link and choose Open with Oracle VM VirtualBox. After installation the ATLAS VM starts without issue.

Second, in this video you get instructions how to log into the VM, which runs Ubuntu 18.04 LTS.
The first step is to “copy paste a command”. However, the instruction screen tells you

"To start the Jupyter server, excecute the command below (only inside the VM!) ./"

However, when I tried that it told me:

bash: ./ No such file or directory

Seems there is a small error. The file name is actually ./ So, running


does start the Jupyter server. The following screenshot shows the situation I found (VM Version was downloaded on Feb 11, 2020, this will certainly be fixed in later versions):

Now, you should be good to go!
