Ubuntu avahi-daemon cannot find "raspberrypi.local"

I am using a ubuntu 16.04 LTS laptop. I have a raspberry pi zero I flashed raspbian onto. I enabled ssh on the raspberry pi, and set it up as an ethernet gadget so I can ssh into it from a micro-usb connection. I can ssh into the pi from my friends macbook, so the raspberry software is configured correctly.

The avahi daemon is up and running:

$ sudo service avahi-daemon status

But I can not ping raspberrypi.local or raspberry.local.

I don't know what that 172.18.94.241 address is, but I can ping it but not ssh it, so I don't think it's the pi.

ifconfig does not show a raspberry pi connection:

sudo ifconfig

I have tried uninstalling and reinstalling the avahi daemon, but it did not work. What am I doing wrong?

I solved it for my Raspberry Pi Zero W the following way:

Network Manager menu -> Edit Connections, edit the new Ethernet connection (for me it was "Wired connection 2"). IPv6 Settings -> Method -> Link-Local Only.

Network Manager should now be able to establish the connection.

$ ifconfig
enp0s20f0u1 Link encap:Ethernet HWaddr 8a:dd:a1:c0:72:c0 inet6 addr: fe80::2f6d:7bde:ad10:d2a7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:165 errors:0 dropped:0 overruns:0 frame:0 TX packets:493 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:30167 (30.1 KB) TX bytes:81949 (81.9 KB)

Check if avahi-daemon has detected the new device by running:

$ avahi-resolve-host-name raspberrypi.local
raspberrypi.local fe80::c813:143e:4bf0:7607

And then:

$ ssh -6 pi@fe80::c813:143e:4bf0:7607%enp0s20f0u1
Linux raspberrypi 4.9.59+ #1047 Sun Oct 29 11:47:10 GMT 2017 armv6l
...

Unfortunately, the simple hostname resolution way does not work:

$ ssh -6
ssh: Could not resolve hostname raspberrypi.local: Name or service not known

Thanks for quantenProjects comment here.
