Hello team !

MUP won't connect through SSH to an EC2 instance running Ubuntu 22.04, running the same command on the same instance config, only running a 20.04 succeed :

Mup version (mup --version): 1.5.8

Mup config, interesting bit : module.exports = { servers: { one: { "host": "ec2-xx-xx-xx-xx.eu-west-3.compute.amazonaws.com", "username": "ubuntu", "pem": "./debug-meteor.pem", } },

Output of command :

Started TaskList: Setup Docker
[ec2-13-xx-xx-xxx.eu-west-3.compute.amazonaws.com] - Setup Docker
node:events:368
      throw er; // Unhandled 'error' event
      ^

This is no problem for the same instance, in the same subnet, with the same permissions and security groups, only running ubuntu 20.04

Cheers !

Yeah, I have the similar problem with another 18.04 LTS works 22.04 LTS does not work. Any idea?

also doesn't work with ssh keys in the keyring:

  servers: {
    one: {
      host: 'xxx.xxx.xxx.xxx', // ip to machine
      username: 'someuser'
    }
  },

manual ssh via ssh [email protected] works. Server us Ubuntu 22.04

Seems to come from an issue with ssh2.

There is a quick fix (at least for my use-case with public keys) but you need to do it manually on the target server: https://github.com/mscdex/ssh2/issues/989#issuecomment-1117074996

The workaround is also mentioned here: https://github.com/zodern/meteor-up/issues/974#issuecomment-1124494397
