** Description changed:

- I'm trying to install Ubuntu 22.04 Server with a user-data file stored
- in a web server to automatic make the installation of the system.
- Happens that when the installation starts it hangs for a while in
- "probe" devices. It keep retrying and /var/log/installer is being filled
- with logs and in these logs there's a `Failed to parse multipath maps
- entry: ok: MMap.__new__() missing 2 required positional arguments:
- 'sysfs' and 'paths'` because before it run the command `multipathd show
- maps raw format %w,%d,%N` from here
- https://github.com/canonical/probert/blob/f34ae3c3f942a9c479fe928911053a302e146251/probert/multipath.py#L69C12-L69C57
- giving the failed message.
