No network connection after upgrade of 16.04
This can be closed now. Just tried to upgrade from clean image.
Everything is fine now.

Title:
No network connection after upgrade of 16.04 arm
Syslog attached. And, yes, I split that line up like you suggested and
there is still no eth0 interface. If you need more you can just ping me
on IRC. Might be faster that way.
root@ubuntu:/home/ubuntu# ifconfig -a
enxb827eb68b434 Link encap:Ethernet HWaddr b8:27:eb:68:b4:34
inet
I. e. splitting the rule still gives you the enxBLABLA interface name
instead of eth0? Unfortunately the interesting parts of the
networking.service journal are cut off (--lines=50 or just attach the
complete "journalctl -b", this is probably more helpful).

Did that but networking.service still fails to start. (I have internet
connection after installing network-manager)
root@ubuntu:/home/ubuntu# systemctl status networking.service
● networking.service - Raise network interfaces
Loaded: loaded (/lib/systemd/system/networking.service; enabled;
Ah, so there is net.ifnames=0 in the kernel command line. So this has
identical symptoms to bug 1593379. Can you please try to change
/lib/udev/rules.d/73-usb-net-by-mac.rules like in
https://anonscm.debian.org/cgit/pkg-systemd/systemd.git/commit/?h
=ubuntu-xenial=f79508898, i. e. split the
root@ubuntu:/home/ubuntu# ls -l /etc/udev/rules.d/
total 0
root@ubuntu:/home/ubuntu# cat /proc/cmdline
8250.nr_uarts=1 dma.dmachans=0x7f35 bcm2708_fb.fbwidth=1920
bcm2708_fb.fbheight=1080 bcm2709.boardrev=0xa02082 bcm2709.serial=0x168b434
smsc95xx.macaddr=B8:27:EB:68:B4:34 bcm2708_fb.fbdepth=32
Please give me the output of
ls -l /etc/udev/rules.d/
cat /proc/cmdline
I'd like to see if cloud-init / the installation intended to disable
ifnames.

eth0 does not exist after update indeed.
root@ubuntu:/home/ubuntu# ifconfig -a
enxb827ebd8ae89 Link encap:Ethernet HWaddr b8:27:eb:d8:ae:89
inet addr:192.168.0.101 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::ba27:ebff:fed8:ae89/64 Scope:Link
UP
Note that it works before upgrade. Everything starts working when I call
dhclient manually. Do you want me to do anything that can give
additional information?

This sounds like some misconfiguration in that image -- apparently
/etc/network/interfaces (or interfaces.d/*) refers to "eth0" which does
not exist?
