[Bug 1779728] Re: Could not upgrade ubuntu 16 to 18

[Brian Murray]

The upgrade failed to calculate because you've installed packages from
the following PPA:

https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test

Please use the tool ppa-purge from the package ppa-purge to remove the
PPA and restore the official Ubuntu versions of the package and then try
the upgrade again.
