Clang error when running `Setup.sh` on Ubuntu 20.04.04

[LDovic]

I get the following error when trying to set up on Linux:

`Registering git hooks... (this will override existing ones!)
Attempting installation of missing package: clang-3.5

• sudo apt-get install -y clang-3.5
  Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  Package clang-3.5 is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source
  However the following packages replace it:
  clang:i386 clang

E: Package 'clang-3.5' has no installation candidate`

Any help would be much appreciated,

Thanks
