I'm trying to play around with secure Teleconsole sessions, using macOS 10.12.6 to host. However, I receive this error when running teleconsole -vv -i JesseTG:

I don't remember whether or not I'm supposed to give the private or the public key, so I tried both.

Actually, this might not be exclusive to macOS. This happens when I try to host a teleconsole instance on CentOS 7.2:

I hate to bump a super old question, but I'm having the exact same issue (on Linux)

It just suddenly happened, it's worked before. I thought it was a problem with Github, but I'm able to use the same keys with other services.

I also tried using the public keys I have on my device (manually adding keys not through the Github API), which returned ssh: no key found

I even ran teleconsole on a VM, that way I could be sure that the problem isn't with my machine, and it still persisted. This led me to believe there was something wrong with my keys in particular, so I tried it using various other accounts. This somehow worked, and opened up a teleconsole session.

❯ teleconsole -i kontsevoy
Starting local SSH server on localhost...

Your Teleconsole ID: 5aq5c34aa04155dceb36ba9d5dc76975a57c8a18
WebUI is not available for key-restricted sessions
~ ❯

(This session is not still running of course.)

This behavior was also exhibited in the VM.

Thinking it was my ssh keys for some reason, I generated multiple new pairs in different formats, none of which worked. I have no idea why this suddenly started happening, but I really would like to try to resolve it.

Solution (For me):

I was using ed25519 keys, which apparently don't work.

My solution was to generate new keys with ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
