Following packages have been kept back

When running the usual…

apt-get update && sudo apt-get upgrade

…I’m greeted with the following:

The following packages have been kept back:
  freepbx17 node-es-module-lexer node-globby node-tap

Everything seems to up-to-date though. Is this something to worry about? Or something that’ll be resolved automagically?

Not feeling like waiting around, I executed the following command:

apt-get install freepbx17 node-es-module-lexer node-globby node-tap

Lots of things happened and at one moment it seemed to break my install completely. After running apt-get update && sudo apt-get upgrade I was greeted by 27 vulnerabilities which I was able to revolve by running the following commands:

fwconsole ma refreshsignatures
fwconsole chown
fwconsole reload

In the end I wasn’t able to dial *97 while *98 did work. And incoming calls were dropped. Meanwhile I rolled back a snapshot.
