Needs to check if target device is big enough for image

[Martin Pitt]

Binary package hint: usb-imagewriter

I used usb-imagewriter to write the current UNR image to my 1 GB usb stick. The details section said "there was an error with dd", and a dialog "There was an error ... (nothing definitive), a log file will be created in your home directory".

However, I do not have any log file in my home directory:

$ ls -l *usb .*usb*
ls: Zugriff auf *usb nicht möglich: No such file or directory
-rw-r--r-- 1 root root 8835 2009-04-16 11:48 .usb-creator.log

.usb-creator.log is unrelated (from usb-creator package).

Nothing in /root/ either.

the log writing function is not implemented yet ...

tracking upstream

The image does not boot. However, that might be a different bug, since previously I just used dd to copy the image to the usb stick, and it didn't boot either.

(I can boot the .img in kvm, and I can use usb-creator to boot the standard Ubuntu image on the same USB stick on the same computers just fine)

I can mount the image (well, it automounts)

  /dev/sdb on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,shortname=mixed,uid=1000,utf8,umask=077,flush)

and cat .disk/info says

  Ubuntu-Netbook-Remix 9.04 "Jaunty Jackalope" - Release i386 (20090420)

$ sudo vol_id /dev/sdb

Ah, now I know:

  1005M 2009-04-20 17:47 jaunty-netbook-remix-i386.img

The previous image was some 890 MB, and fitted on my 1 GB stick just fine. Now it grew dramatically, and thus simply doesn't fit on my 1 GB stick any more.

Thus usb-imagewriter should check the available space and don't allow me to write the image on it. usb-creator does this well.

[Oliver Grawert (ogra)]

yes, the size check is a planned feature for karmic

[Daniel Hollocher (chogydan)]

The original error I believe is cause by a lack of permissions to access the usb drive.

Also, it would be nice if you renamed the executable from imagewriter to usb-imagewriter. IMHO, it makes more sense for the command to match the package name.

[Martin Pitt (pitti)]

As I already said, the original error is about the target device being too small for the image.

I keep this open because usb-imagewriter should check this in advance, like usb-creator.

imagewriter is dead, closing ...
