Public bug reported:

This is a regression.

Upon upgrading 16.04 -> 16.10. Wired connection provided by
"RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller" has stopped
working.

Quickly looked around for possible solution, and decided to go on with
upgrade to 17.04, since it was my initial upgrade target anyway, and
wireless on the system continued to function. So, ended up in this
situation: running 17.04, wireless adapter is working, while wired does
not work any more.

Extra observation: I've also tried live session from USB based on 17.04
ISO-image, wired network adapter just works in the live session.

Conclusion: it is a software issue.

Note that similar problem was reported be other user on the forum:
