md5sum check of UNR image fails in one file

[Nick Demou]

Binary package hint: ubuntu-netbook-remix

if I run:
   md5sum -c md5sums.txt
I get this error:
   md5sum: ./pool/main/p/ppp/ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb: No such file or directory

the correct file is indeed there but with a different name (ppp_2.~D if I remember corectly)

[Colin Watson (cjwatson)]

The problem is probably a messy interaction between the ~ in that file name and VFAT's long file name rules.

[Colin Watson (cjwatson)]

A release note may be called for here. This causes the md5sum check to fail, and also causes ppp to be uninstallable from the image (although this doesn't break installation; ppp is provided as an additional convenience for users who need it to get on the network). It shouldn't be fatal otherwise.

[João Manuel Rodrigues (jmr)]

I confirm this bug.

After mounting (as VFAT) on a ubuntu 6.06 system, the correct file appears as:
ff0358bc3eb43e9420a7f009482c278a ./pool/main/p/ppp/PPP_245~.D

whereas md5sum.txt contains:
ff0358bc3eb43e9420a7f009482c278a ./pool/main/p/ppp/ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb

I can confirm bug #366086 in Jaunty in the Ubuntu remix (eee pc 1000). Although it is marked there as a duplicate of this one, I am not sure. I posted a comment about this in
http://ubuntuforums.org/showthread.php?t=1143377

By the way, the "live usb" works in spite of this, but the camara and the microphone don't.

[Adrian S. (adrianmatematico)]

I rechecked. The live-usb can be made to work with the camera and the mic after enabling the camera in the BIOS and after going to Volume Control->Preferences, enabling capture, and then unmuting the mic and raising the record level. Thus I don't know what the lack of the file pool/main/p/ppp/ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb means.

[Daniel Hollocher (chogydan)]

@Adrian: this bug only results in the inability to install the ppp package from the image (you can still install it from the repositories, ie, after you have installed your system). It won't have anything to do with your hardware working as you described.

[Steve (stupendoussteve-deactivatedaccount)]

If you rename the file on the USB stick the check will pass, and as a bonus the name will stick if you unmount and remount (though fsck.vfat will tell you it is orphaned). The file is named ppp_45~.d even on the .img when loop mounted.

Discovered this when I created a UNR DVD image (here I thought *I* was the one with the problems).

[Adrian S. (adrianmatematico)]

I renamed the file and the check passed. You are right, the camera and the mic are not related to this bug. Thank you very much!

[Hilikus (hilikus)]

i could not rename the file, it said permission denied when i tried to
creating new files in the same dir was allowed though

I tried to reproduce using dosfstools + mtools:
rm -f vfat.img; mkdosfs -F 32 -C vfat.img 102400; touch ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb; mcopy -i vfat.img ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb ::ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb

but loop mounting this vfat from karmic just works

[Loïc Minier (lool)]

Also works with
rm -f vfat.img; mkdosfs -F 32 -C vfat.img 102400; touch ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb; mmd -i vfat.img pool; mmd -i vfat.img pool/main; mmd -i vfat.img pool/main/p; mmd -i vfat.img pool/main/p/ppp; mcopy -i vfat.img ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb ::pool/main/p/ppp/ppp_2.4.5~git20081126t100229-0ubuntu2_i386.deb

[Alexander Sack (asac)]

bug 481482 tackles some regression surrouding the filename mangling. Its not clear to me why that would trigger this ppp bug though.

[Loïc Minier (lool)]

Marking as invalid in ubuntu-release-notes for now since this has been open since 04/2009 and we moved to ISOs now.

[Steve Langasek (vorlon)]

From the bug log I understand this was only an issue with vfat images, which are no longer something that we produce in currently supported releases. Closing wontfix.
