Hi, I am trying to build the Docker Image as per the instructions in the gitlab readme
https://gitlab.com/voxl-public/system-image-build/voxl-build

On the step 
```
docker build -t voxl-build -f ubuntu-xenial.Dockerfile .
```
I get the following error:
```

```

I have gotten this error in Ubuntu 20 and a clean install of Ubuntu 18

This is with a fresh pull from the repo

@Thomas-MacNamara The issue should be fixed now, go ahead and pull the changes and give it another try.

I can confirm it does work now.

Also not sure if it helps but after running through this about 10 times I got tired of copy and pasting the steps from the docs and modified the last line of the docker.run

```
-w /home/user ${optImg} /bin/bash -c "echo doing the first steps from the docs ; cd $optDir ; sudo -S <<< "user" chown user . ; rm -rfv $optDir ; echo user; source /home/user/build.sh $optDir; $SHELL"
```
This just does the rest of the steps at once and starts building

I am sure most people wouldn't need it but i might be useful for someone
