Lost SSH access to ubuntu snappy core

I have ubuntu snappy core installed on my dragonboard. I set it up using SSO. It worked fine to ssh to the dragonboard from the desktop computer with ssh keys and no password.

Suddenly after years, when I ssh to snappy core it now prompts for a password that I don't have... what am I doing wrong?

Check that the Ubuntu Core system still resides at the same IP address. You might be seeing a different system on that network, and the IP addresses have shifted around.

Thanks for the reply. That is a good thought, however I checked and it is still under the same ip address. Is it possible the ssh key got changed somehow? Or can I connect a new SSO key?

I have two answers to this question:

I found out that I was logging in with the wrong username. I was trying to login as the user who owned the ssh key, but I was supposed to login with the username of the core system. I forgot that somewhere along the line.
I discovered this because I wanted manually update the keys by mounting the snappy sd card on another system. Then editing /writable/user-data/username/.ssh/authorized_keys

This is where I rediscovered the username on the snappy core system was different from the username on my desktop.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
