title: How can I install gcc 7.3 for ubuntu 16.04?
body: <p>It looks like Jonathan F's gcc-7.3 build doesn't work for Ubuntu 16.04. amd64 build has a failed status. See <a href="https://launchpad.net/~jonathonf/+archive/ubuntu/gcc-7.3" rel="noreferrer">here</a>. </p>
  
  <p>At this point Ubuntu Toolchain <a href="https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test" rel="noreferrer">here</a> only has gcc-7.2. </p>
  
  <p>Are there any relatively easy alternative ways to upgrade existing gcc to gcc 7.3? </p>
  
  <p>Thanks.</p>
