subiquity getting confused by ntfsresize? (seems to restart after hitting 'Please make a test run using both the -n and -s options before real resizing!')

[Carl Booler]

Trying to install Ubuntu 24.04 LTS on my iMac 2017, Retina 5K, 27 inch (Apple Inc. iMac18,3).

I am able to boot into the "Try Ubuntu", however the installer would either freeze, crash or show "Something went wrong" window.

No logs show in the installer UI.

Here are the logs when I run it from terminal:

```

```

In the above case I get "Something went wrong" window showing.

When it crashes I get a different log:
```

```

Other things to note:
I am able to successfully start the installation on another machine
I am able to install Ubuntu 22.04.4 LTS on the iMac
I have tried with a couple of different working USB sticks.

Thank you for your bug report. Could you add the logs from/var/log/installer after getting the problem?

[Carl Booler (casual-ubuntu-bug-reporter)]

First attachment: when the UI shows that there is an error.

[Carl Booler (casual-ubuntu-bug-reporter)]

Second attachment, the installer crashed.

[Sebastien Bacher (seb128)]

Thanks for the log, those are from the frontend though and just tell us that the backend crashed, could you also add the subiquity-debug.log from the same directory?

[Carl Booler (casual-ubuntu-bug-reporter)]

subiquity-debug.log keeps getting generated even if I don't do anything.

I attached a zip of the logs from that directory. I tried to limit it to just for when it crashes.

[Sebastien Bacher (seb128)]

Thanks. It's a bit weird indeed, it seems subiquity keeps restarting or something but the log doesn't tell why?

They include those mention though

2024-05-29 23:08:43,457 DEBUG probert.utils:50 You might resize at 41659891712 bytes or 41660 MB (freeing 384081 MB).
2024-05-29 23:08:43,457 DEBUG probert.utils:50 Please make a test run using both the -n and -s options before real resizing!
2024-05-29 23:08:43,457 DEBUG probert.utils:52 <empty stderr>

so maybe they get confused by the ntfsresize return?
