Boot needs up to 7 minutes on Ubuntu 16.04

[pfeerick]

Hi pfeerick,

thanks for your reply, but it doesn't fixed the problem.
I changed the "timeout" in /etc/dhcp/dhclient.conf from 300 to 10 seconds.
This solutions doesn't fixed the problem, but this is a "good enough" solution for me.

Best regards
Julian

My apologies... I mean to say "replace", not add :-O

in your /etc/network/interfaces file, if it currently contains the auto eth0 line, replace it with allow-hotplug eth0 

If /etc/network/interfaces contains a line saying source-directory /etc/network/interfaces.d  you instead need to instead be looking at and editing /etc/network/interfaces.d/eth0

That should fix cure your no-ethernet boot woes.
