ubi-partman fails with error code 141 during install (14.04 beta 2)

[Julien Gabet]

When running ubiquity from terminal, throws this error and never gets to the partitioning window.
When running it from the sidebar, doen't throw error but hangs before partitioning window (to never get there eventually)

It's very annoying, I seem to understand it searches for a RAID pool (I have a SSD), but I made sure to have s-ATA set to AHCI mode in the EFI/BIOS setup before booting the installer (and there's no Intel Fast Storage option there by the way)

Note: tried Latest daily (April 5th), same result...

That issue is wierd, it seems my partition tables were somehow corrupted (on both disks at the same time, wtf?), but not completely (I could still boot windows, even install windows again, and I couls see all partitions in GParted and create new ones with no problem or error whatsoever).
Backing up my data on an other drive and re-creating new partition tables for both disks (gpt, same as before) did the trick.
I wonder though why GParted could see the contents of the disks and partman couldn't (or at least thought the disks were not eligible to install Ubuntu...)

Thanks for your report.

There is a partition with non-ascii characters and in debug log there is is UnicodeDecodeError exception:
Exception caught in process_line:
Traceback (most recent call last):

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 64: invalid continuation byte

Which could be due to the non-ascii label. Setting to incomplete and I'll will try to reproduce the case.

[Jean-Baptiste Lallement (jibel)]

I failed at reproducing this issue because I couldn't set a label on either an ntfs (with ntfslabel) or ext4 (with e2label) that parted_server would see. However there is enough information in the bug report to set it to triaged.
