missing unzip dependency for install script

[thomaspeyrucain]

If unzip is not installed the installation script fails with this error:

Torch version not defined, version 1.9.0 will be installed.
For a specific Torch version please define TORCH_VERSION with 'export TORCH_VERSION=x.x.x'

Hey @thomaspeyrucain, thanks for reporting this. Could you provide some additional information?

• Are you attempting a full toolkit installation on a desktop by cloning and running the installation script as described here?
• After failing, did you install unzip, then retried the installation and it ran successfully? If so, how exactly did you install unzip?

Hello @tsampazk ,

• We tried a full toolkit installation on a docker container with noetic installed
• After installing via apt install unzip we retried and it was successful

Thanks! It seems that most systems that we use have unzip pre-installed. I think we can install unzip along other base ubuntu dependencies, which should do the trick.
