Installation issue with oar-docker and oar3.0.0.dev6

[nikosT]

I use the latest version (which currently is dev6). When I run the following:

1. mkdir oar3 && cd oar3
2. oardocker init -e buster build
3. git clone --depth 1 --branch 3.0.0.dev6 https://github.com/oar-team/oar3.git
4. oardocker install ./oar3

On step 4, I receive the following error before installation is finished.
