It was working before but now it stopped working. Even in Ubuntu SDK I can't run my application directly to my device...though I'm not sure they are related. The error is:

Command: open "phablet@192.168.1.7" 22 Error: Disconnected: No supported authentication methods available (server sent: publickey) Error: Could not connect to server

My device is Nexus 7 2013(flo) with Ubuntu Touch 14.10 r153. I installed it through MultiRom and I actually did a fresh install but still no luck.

    You can get ssh to be verbose by adding -v on the command line. The option can be given multiple times to increase verbosity. You will be able to see which authentication methods there are support at both ends. – jhilmer Jul 27 '14 at 17:01
  • There are/were steps to enable SSH, but they have changed recently. I will research further. Meantime, check out: https://lists.launchpad.net/ubuntu-phone/ (which is where the changes were announced. ) – david6 Jul 28 '14 at 07:58
  • I already enabled it before. I can't see anything from the mailing list about some changes on ssh. I tried this in both WinSCP on Windows and FileZill in Ubuntu so I think it's with Ubuntu TOuch or probably on my network/router? – user1173805 Jul 30 '14 at 15:18

    *Did you solve this?* You needed to read: [Ubuntu-phone] Developer heads up ... change in ssh handling on the phone (on 23/05/14 02:51) Steps: create SSH key (on workstation), enable SSH on device, copy public key to device, connect. – david6 Aug 03 '14 at 02:32
  • I've read that but I still can't figure out how to login vie FileZilla/WinSCP. Same error occurs even if I already loaded the private key in the configuration of FileZilla. – user1173805 Aug 18 '14 at 14:07
  • See SSH Ubuntu Touch for a working solution. As always with password-less authentication you need to place a /home/phablet/.ssh/authorized_keys file (with a public key of the PC you're using to access the Ubuntu Touch device) on your device. – Peterino Feb 11 '16 at 23:43

I'm having the same issue, on the same tablet. I am currently using the developer channel, but not proposed. OS: 15.04 r2. It won't find my .pem key, however after running the commands below, I was able to get my computer to reject my tablet connecting to it via ssh. Please excuse typos

user@ubuntu:~$ adb shell

phablet@ubuntu-phablet:~$ android-gadaget-services enable ssh

phablet@ubuntu-phablet:~$ ssh...

I found out that the build in backup software, which I can't get to work, doesn't allow backup over ssh, if you use the adb interface. The adbd interface does nothing, but acts like it is performing some task.
