Droplet has no interfaces after update?

dot in 50-cloud-init.cfg makes ifup ignoring that file. after rename - all works. I am looking for resolution of work-a-round so far. One w-a-r is a symlink on .cfg file

Hello Friend! I have the same problem. How did you solve it?

@hansen That’s what I ended up doing, thanks for the help

@hansen

I ran cat /proc/version and it returned that I was on the affected kernel. I tried reverting to the previous kernel 4.4.0-66-generic and 4.4.0-59-generic.

Still no internet connection.

I haven’t touched either of the files listed.

Hi @markwatneyy

It sounds like an update that went really wrong. If you run the service networking restart again, can you then post the last 50 lines from your syslog:

tail -50 /var/log/syslog

Also, let’s have a look at /etc/networking/interfaces to see if it still contains your eth0 setup and the correct IP-address.
