I am using nodesource repositories to install nodejs on Ubuntu Xenial and when required to install package npm, apt tries to install the actual npm package. This baffles me, because the installed nodejs package provides npm as a virtual package:
Package: nodejs
Version: 8.11.2-1nodesource1
Architecture: amd64
Maintainer: Chris Lea <chl@nodesource.com>
Installed-Size: 59949

Description: Node.js event-based server-side javascript engine
Node.js is similar in design to and influenced by systems like
Ruby's Event Machine or Python's Twisted.
.
It takes the event model a bit further - it presents the event
loop as a language construct instead of as a library.
.
Node.js is bundled with several useful libraries to handle server tasks :
System, Events, Standard I/O, Modules, Timers, Child Processes, POSIX,
HTTP, Multipart Parsing, TCP, DNS, Assert, Path, URL, Query Strings.
My understanding is that upon apt-get install npm, the system should state that package npm is already installed, but it tries to install a npm package which conflicts with nodejs. Furhtermore, listing installation candidates with apt-cache policy does not list the nodesource package as a candidate, which according to my understanding is wrong:
# apt-cache policy npm
npm:
Installed: (none)
Candidate: 3.5.2-0ubuntu4
