Getting multiple different errors while trying to log into a remote server server (From MacOS or Linux Rocky8).

could not set shell prompt (received: b"unset PROMPT_COMMAND\r\nPS1='[PEXPECT]\\$ '\r\nset prompt='[PEXPECT]\\$ '\r\nprompt restore;\r\nPS1='[PEXPECT]%(!.#.$) '\r\n", expected: '\\[PEXPECT\\][\\$\\#] ').

could not synchronize with original prompt

could not set shell prompt (received: b"unset PROMPT_COMMAND\r\nPS1='[PEXPECT]\\$ '\r\nLast login: Tue Oct 29 14:22:38 2024 from 10.166.122.120\r\r\n[user@remoteserver ~]$ \r\n[user@remoteserver ~]$ \r\n[user@remoteserver ~]$ \r\n[user@remoteserver ~]$ \r\n[user@remoteserver ~]$ unset PROMPT_COMMAND\r\n", expected: '\\[PEXPECT\\][\\$\\#] ').

Script I am using to login,

      attempt = 0
      while attempt < 5:
              try:
                  s = pxssh.pxssh(options={"UserKnownHostsFile": "/dev/null", "StrictHostKeyChecking": "no"},
                                  timeout=60)
                  s.login(host, 'user', ssh_key=get_ssh_key(), sync_multiplier=10, port=22)
                  s.sendline('sudo systemctl restart servicename')
                  s.prompt()
              except Exception as e:
                  logging.info(f"Attempt {attempt + 1}: {e}")
                  if 'could not synchronize with original prompt' in str(e):
                      # Optionally unset the prompt or adjust as needed
                      print("Adjusting prompt...")
                      s.prompt_command = None  # Unset the prompt_command
                      # Optionally modify the prompt pattern
                      s.prompt = pexpect.EOF
                  attempt += 1

So you have OpenHands running and you tell it to login to a remote server of some kind? That's probably unsupported. Not sure what the use case is.
