Invalid package information

After updating your package information, the essential package
'ubuntu-minimal' could not be located. This may be because you have
no official mirrors listed in your software sources, or because of
excessive load on the mirror you are using. See /etc/apt/sources.list
for the current list of configured software sources.
In the case of an overloaded mirror, you may want to try the upgrade
again later.

This is likely because you installed nodejs packages from nodesource and those packages are usually a greater version number than the ones provided by the official Ubuntu archive. Subsequently, you'll need to remove those nodejs packages and try the upgrade process again.
