bug: possible ssh2-classic problem

[jirikrepl]

Hello, I encountered this problem when I updated to version 1.5.9.
I used v1.5.8 without any problems.
In the source code I saw you changed shh2 package for ssh2-classic.

This change seems to cause some problems for me.
Strange thing is, I can deploy fine with mup deploy.
But if I schedule deployment with at command, I get this error.

Mup version (mup --version): 1.5.9

Mup config

  "servers": {
    "one": {
      "host": "1.2.3.4",
      "username": "root",

    }
  },
  "app": {
    "name": "my-app",
    "path": "../../",
