Ubuntu autoinstall failed : block probing failed

Question

I'm trying to autoinstall an Ubuntu 22.04 server and I'm using, for now, a rather minimalist user-data file, that I copied on a usb stick (created with sudo mkfs.vfat -I -F 32 -n 'CIDATA' /dev/sdb)

I provide below the content of the two files on the usb stick. Then I boot and start the auto-install (adding the autoinstall option to the boot command line).

Unfortunately, the installer stops with some errors :

...
start: subiquity/Mirror/apply_autoinstall_config
start:   subiquity/Mirror/apply_autoinstall_config/waiting
finish:    subiquity/Filesystem/_probe/probe_once: cancelled
start:   subiquity/ErrorReporter/1687822728.270903587.block_probe_fail/add_info
start:   subiquity/Filesystem/_probe/probe_once: restricted=True
finish:    subiquity/Filesystem/_probe/probe_once: restricted=True
finish:    subiquity/ErrorReporter/1687822728.270903587.block_probe_fail/add_info: written to ..
finish:  subiquity/Filesystem/_probe
..

And after these finishing lines, the autoinstaller givens me access to a terminal and the install is stopped. And I do not know what I can do basically to solve this issue. Actually, I do not know if this an error from, say, subiquity and I can fill an issue, or a configuration issue on my side.

The meta-data and user-data files are given below :

        access-points:

            password: "MY_WIFI_PASS"

Thank you for your help.

I'm not very familiar with the autoinstall. I tried to look into the /var/log/installer and /var/crash directories.

grepping "ERROR" in the crash file, I find few 3 errors :

ERROR probert.network:768 set_link_flags failed
ERROR root:37 finsih subiquity/Filesystem/_probe/probe_once: FAIL: cancelled
ERROR block-discover:596 block probing failed restrcited=False

Then in /var/log/installer/block, in the discover.log file, I see, among other logs, one raise exceptions.TimeoutError() from l590 in subiquity/server/controllers/filesystem.py

I'm wondering if this is the origin of the failure of the autoinstaller.

In the following lines in the discover.log file, after the raised exception, I see some elements :

Extracted multipath maps fields: ['ok']
Failed to parse multipath maps entry: ok: __new__() missing 2 required positional arguments: 'sysfs' and 'paths'
Extracted mutlipath paths fields: ['sda', 'WD-WX91AB4DFAJV', '[orphan]', '[undef]', 'ata-1.00', '[undef]', '[unded]', '[unded]']']
...

and at the very end, a merged storage config where I see the sda drive, the USB , etc.. I do not know if these elements are relevant.
