Is it possible to upgrade my 16.04LTS system to 17.10 without setting up a new system?

I'm search for a solution like apt-get upgrade.

This looks like a simple "Just google it" question. Anyway, you will get step-by-step instructions on Upgrade Ubuntu desktop | Ubuntu tutorials.

This boils down to:

  • make a backup
  • run software-properties-gtk, in "update" tab set "Notify me of a new Ubuntu version" dropdown menu to "For any new version". This is the part that clobbers the support duration.
  • run update-manager
  • Click Upgrade and follow the on-screen instructions.

update manager offering upgrade to 17.04

Yet I wouldn't recommend you to do it and second @sudodus comment which warns you that by doing so you'd replace a long-term-support system with a system supported only for a short time.
