Currently, you can use:

apt:
  sources:
    - ubuntu-toolchain-r-test
    - sourceline: 'deb https://apt.llvm.org/xenial/ llvm-toolchain-xenial-9 main'
      key_url: 'https://apt.llvm.org/llvm-snapshot.gpg.key'
  packages:
    - clang-9

See https://github.com/taocpp/sequences/blob/master/.travis.yml
