Hello ! At work I need to use an ubuntu 20.04 based docker image built by our org, and we use vagrant to easy the way to load and start the image. I'm not able to do "vagrant up", since it seems the host can't connect to the container (guest):

After the SSH authentication error, apparently because none of the attempted key authentication methods worked. Weird thing, on ubuntu 22.04 there's no problem. On arch is that I see the error. BTW, I tried "config.ssh.disable_deprecated_algorithms" [1] set to true on the Vagrantfile, and it doesn't help. I see nothing particularly curious on the Vagrantfile. For SSH:
# SSH options
sdk.ssh.username = "<container_username>"
sdk.ssh.forward_agent = true
sdk.ssh.pty = true
sdk.ssh.forward_x11 = true
sdk.ssh.insert_key = false
Disabling deprecated algorithms since Arch has obviously a newer openssh, but again, that didn't help. It's weird that on arch the SSH authentication fails... I've created other docker containers based on ubuntu, pretty similar on this SSH Vagrantfile config, and no issues. On the other hand, I've also used other docker containers. Actually there are 2 from the org I work, that I would like to use on my arch box, but I just cant, currently relying on remote VMs... Thanks for any hints... -- Javier [1] https://developer.hashicorp.com/vagrant/docs/vagrantfile/ssh_settings
