storage probe validation - "Couldn't find partition entry in table"

[Dan Bungert]

Several users in private bugs have run into a common problem, where curtin fails to parse the initial storage configuration with the following error:

  File "/snap/ubuntu-desktop-installer/939/bin/subiquity/subiquity/server/controllers/filesystem.py", line 852, in _probe
    await asyncio.wait_for(self._probe_once_task.task, 90.0)
  File "/snap/ubuntu-desktop-installer/939/usr/lib/python3.10/asyncio/tasks.py", line 445, in wait_for
    return fut.result()
  File "/snap/ubuntu-desktop-installer/939/bin/subiquity/subiquitycore/context.py", line 148, in decorated_async
    return await meth(self, **kw)
  File "/snap/ubuntu-desktop-installer/939/bin/subiquity/subiquity/server/controllers/filesystem.py", line 834, in _probe_once
    self.model.load_probe_data(storage)
  File "/snap/ubuntu-desktop-installer/939/bin/subiquity/subiquity/models/filesystem.py", line 1548, in load_probe_data
    self.reset()
  File "/snap/ubuntu-desktop-installer/939/bin/subiquity/subiquity/models/filesystem.py", line 1131, in reset
    self._orig_config = storage_config.extract_storage_config(
  File "/snap/ubuntu-desktop-installer/939/lib/python3.10/site-packages/curtin/storage_config.py", line 1315, in extract_storage_config
    found_cfgs, found_errs = parser.parse()
  File "/snap/ubuntu-desktop-installer/939/lib/python3.10/site-packages/curtin/storage_config.py", line 634, in parse
    entry = self.asdict(data)
  File "/snap/ubuntu-desktop-installer/939/lib/python3.10/site-packages/curtin/storage_config.py", line 788, in asdict
    raise RuntimeError(
RuntimeError: Couldn't find partition entry in table

The issue can be reproduced with dry-run based on the ProbeData.txt in LP: #2017524 and presumably others.

I've merged many bug reports with similar symptoms to this bug report. I'm not sure if they all have the same root cause though.

If you are one of the affected people, we'd be interested to know what software you used to create the installation media. If you're using Ventoy or another software that allows to "dynamically" boot the installer, we'd be happy to know as well please.

Thanks!

I tried Ventoy and Rufus.

The problem was due to a disk that was converted as a dynamic disk in
Win 11. After I converted it back to a basic, I could install Ubuntu (as
usual) as dual boot with Win 11.
