Bug#766964: grml2usb (0.14.10) :fatal error

This issue is caused by certain USB devices which seem to have specific data on them causing python-parted to fail to properly recognize them. Sadly we didn't manage to identify the reponsible data on the usb device that causes this behaviour, but as soon as the device gets overwritten with zeros (dd if=/dev/zero of=/dev/sdX) the issue is gone and grml2usb/python-parted work as intended. We just commited a workaround to grml2usb to not fail in this situation and display a warning message and fall back to some legacy code instead. If someone should be able to reproduce this behaviour we'd be *very* interested in a dump of the USB device's data, please contact us then! Thanks everyone for your feedback and help in resolving this issue! regards, -mika- signature.asc Description: Digital signature

Package: grml2usb Version: 0.14.10 Followup-For: Bug #766964 Not sure if it may be related, but today I got the Fatal: 'NoneType' object has no attribute 'getFlag' error when trying to run grml2usb via sudo: $ sudo grml2usb grml96-full_2014.11.iso /dev/sdb1 But everything worked fine when grml2usb was run from a full root session: $ sudo su - # grml2usb grml96-full_2014.11.iso /dev/sdb1 -- Michał Politowski Talking has been known to lead to communication if practiced carelessly. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#766964: grml2usb (0.14.10) :fatal error
Dear Evgeni, I succeeded to install grml on the same usbstick, doing the following: 1. the partion label was loop. I changed it to msdos 2. I formatted /dev/sdb1 with mkfs.fat instead of mkfs.vfat After this df was as fast as it should be (I used /dev/sdd1 before, since the other device-names were used otherwise) The command 3. grml2usb --bootoptions=lang=de --bootoptions=nodhcp --grub grml64-full_2014.03.iso /dev/sdb1 resulted in: Executing grml2usb version 0.14.10 Using ISO /tmp/grml64-full_2014.03.iso Identified grml flavour grml64-full. Copying files. This might take a while Installing default MBR mount: special device /dev/sdb1 does not exist Fatal: Error executing mount (no filesystem on the partition?) Cleaning up before exiting... Fatal: [Errno 2] No such file or directory: '/tmp/grml2usb3oHiCX' The grml-files were copied on /dev/sdb1, but the stick didn't boot. I tried then 4. grml2usb --bootloader-only --bootoptions=lang=de --bootoptions=nodhcp --grub grml64-full_2014.03.iso /dev/sdb1 The output was Executing grml2usb version 0.14.10 Using ISO grml64-full_2014.03.iso Identified grml flavour grml64-full. Installing default MBR Installing grub as bootloader /usr/sbin/grub-install: Fehler: Mehr als ein Installationsgerät?. Installing for i386-pc platform. /usr/sbin/grub-install: Warnung: Dateisystem »fat« unterstützt keine Einbettungen. /usr/sbin/grub-install: Warnung: Einbettung ist nicht möglich. GRUB kann in dieser Konfiguration nur mittels Blocklisten installiert werden. Blocklisten sind allerdings UNZUVERLÄSSIG und deren Verwendung wird daher nicht empfohlen.. installation beendet. Keine Fehler aufgetreten. Note: grml flavour grml64-full was installed as the default booting system. Note: you can boot flavour grml64-full using 'grml64-full' on the commandline. Finished execution of grml2usb (0.14.10). Have fun with your Grml system. Now a had a bootable gmrl-stick Best regards, Martin

I created the very same setup here, and parted detects the partition
just fine.

Welcome to fdisk (util-linux 2.25.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0xa2378f95.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p):
Using default response p.
Partition number (1-4, default 1):

Last sector, +sectors or +size{K,M,G,T,P} (2048-2097151, default 2097151):
Created a new partition 1 of type 'Linux' and of size 1023 MiB.
Command (m for help): t

Changed type of partition 'Linux' to 'DOS secondary'.

Parted by hand:
import parted
d = parted.getDevice('/dev/loop0')
disk = parted.Disk(d)
part = disk.getPartitionByPath('/dev/loop0p1')
part
parted.partition.Partition object at 0x7f0fb9643810
print part.getFlag(parted.PARTITION_BOOT)
False
I observed that df needs very log to read informations from /dev/sdb1
That's odd.
Could you try another USB drive with the same partition layout? Just to
be sure?
