Title:
  subiquity server using probert to execute `multipathd list maps`
  returning 'ok'  and parse fails then installer fails

Status in subiquity package in Ubuntu:
  New

Bug description:
  I'm attempting to install Ubuntu 22.04 Server using a user-data file
  stored on a web server to automate the installation process. However,
  during the installation, it hangs for a while at the "probe" devices
  stage. It continuously retries, and the /var/log/installer file gets
  filled with logs. Within these logs, there's an error message stating:

  Failed to parse multipath maps entry: ok: MMap.__new__() missing 2
  required positional arguments: 'sysfs' and 'paths'

  This error occurs because the installation process tries to execute
  the command multipathd show maps raw format %w,%d,%N from the
  following GitHub link:
  https://github.com/canonical/probert/blob/f34ae3c3f942a9c479fe928911053a302e146251/probert/multipath.py#L69C12-L69C57.

  System Information:

      Ubuntu-Server 22.04.3 2024.02.17 (Cubic 2024-02-17 18:56)

  I expected the installation to proceed normally without continuous
  retries.
