Node: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by node)

Hi,

When attempting any kind of nodejs build with Travis, I get the following errors:

node: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by node)
node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by node)
node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by node)
node: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by node)
node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by node)
node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by node)

Here is my .travis.yml:

language: node_js
node_js: lts/*
script:
  - npm run build || travis_terminate 1;

I have checked through the travis docs and this config looks to be valid can somebody explain what setting(s) I am missing?

Thanks
