When startin fresh new devspace there are no ./ssh/known_hosts. This cause push build failure

This is because:
The authenticity of host 'github.com (192.30.252.123)' can't be established.

to solve that problem:

From https://trello.com/c/z5LrlWMy/275-spaces-work:
ssh-keyscan github.com >> ~/.ssh/known_hosts
thank you that works ;-)
looks like too early enthusiasm. I started fresh devspace deployment and having the same problem now. Running manually
bash-4.1$ /home/slave/.local/bin/scc merge develop --no-ask --reset -S success-only --push develop/merge/trigger
doesn't ask me the above question but still failing
@joshmoore thank u, it work!
@joshmoore how is this any safer than just answering the prompt with yes?
Either way, we are trusting that there is absolutely no corruption in our connection to github.com, what this security feature is made to address I thought?
Hi @Xerus2000. You're right that ssh-keyscan github.com >> ~/.ssh/known_hosts isn't safer at all. What this issue doesn't make clear though is that @aleksandra-tarkowska was looking for an automated way to start a fresh docker container which hasn't yet been primed with a known_hosts yet, i.e. there is no prompt that we can answer. This is a workaround at best.
Just a note - this error can happen if You forgot to add Your ssh key to the repo You are trying to communicate with :)
I've been having this problem, but it doesn't ask if I want to continue. It just hangs there. I ran the ssh-keyscan command and I see the entry in the known_hosts file, but I still get the authenticity error. Even restarted my computer to no avail.
I also tried the test: ssh -T git@github.com and got this output:
<name>@<machine> ios-sportsbook % ssh -T git@github.com
Warning: Permanently added the RSA host key for IP address '140.82.114.3' to the list of known hosts.
Hi <githubUser>! You've successfully authenticated, but GitHub does not provide shell access.
Tried my git clone, but still got the error: The authenticity of host 'github.com (140.82.114.3)' can't be established. And it never asks if I want to continue
Hmm.... sounds like there's something else going on here. By my count, you've ok'd the authenticity at last twice but it's still not asking for confirmation which is weird. The only thing I can think of off-hand is if there are different users/machines/contexts by which known_hosts somehow changes.
I will note that GitHub itself has improved there docs around this in case there's anything there that might help you:

Just typing "yes".

ssh-keyscan github.com >> ~/.ssh/known_hosts
Your amazing man , you made my day , thanks a lot
ssh-keyscan github.com >> ~/.ssh/known_hosts just leads to another error

Just run ssh git@github.com instead
Hi @mpalenov. Sounds like there's more involved in your case. For example, the ssh-keyscan github.com >> ~/.ssh/known_hosts should have prevented npm ERR! Warning: Permanently added the ECDSA host key for IP address '140.82.121.4' to the list of known hosts. Perhaps it was run as a separate user or in a separate context? Also the error npm ERR! git@github.com: Permission denied (publickey). most likely comes from a missing SSH key somewhere. But if you are in an interactive shell, you're right: "Just run ssh git@github.com instead" 👍
From https://trello.com/c/z5LrlWMy/275-spaces-work:
ssh-keyscan github.com >> ~/.ssh/known_hosts
Thank you so much for this.
I've been haunted by the error for quite some time.

Thank you!
