Hi everyone. I suffered too, but here is my solution.
This bug appears to affect old RTL8111/8168/8411 devices.
To check if you are affected:
# lshw -class network | grep product
product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller # <---
you might be
# lsmod | grep r8169
r8169 81920 0 # <--- you are affected because r8169 should
not be loaded, r8168 should be but appears to not come with Ubuntu 17.04...
To solve this problem you need to have DKMS installed:
# dpkg -l | grep dkms
ii dkms 2.3-3ubuntu1
all
Dynamic Kernel Module Support Framework
You need to download
https://packages.ubuntu.com/zesty/all/r8168-dkms/download and bring it
across to the machine affected and then install it on there:
# dpkg -i r8168-dkms_8.043.02-1_all.deb
I am saying this since it might be that you struggle to get anything
useful out of apt install etc because of lack of proper routing via your
local network gateway. Of course the alternative is to just do:
# sudo apt install r8168-dkms
For those needing a bit more help, see a more detailed guide @

It also explains why this problem is happening.
