How can I install gcc 7.3 for ubuntu 16.04?

Question

It looks like Jonathan F's gcc-7.3 build doesn't work for Ubuntu 16.04. amd64 build has a failed status. See here.

At this point Ubuntu Toolchain here only has gcc-7.2.

Are there any relatively easy alternative ways to upgrade existing gcc to gcc 7.3?

Thanks.

Please see detailed answers to this issue here.

Essentially you need to use a different ppa channel. This has worked for me for gcc 7.3 on ubuntu 16.04.
