Seeing this problem on kernel 2.6.32-20 64 bit- 4 gig ram intel duo core 2

[frenchy82 (cartes)]

Same problem with a fresh install of ubuntu 10.04 final

[frenchy82 (cartes)]

hum... i'm afraid that the problem come from libmtp8

Using libmtp8 package from karmic solve the problem for me

[Daniel (dan-voipfamily)]

Did you install libmtp8 from karmic over the currently installed version? I tried removing it and it wanted to uninstall rhythmbox as well. Did you do that and then reinstall rhythmbox?

[Kevin C. (kedoc)]

Yes, in order to install the Karmic version, you have to before uninstall your current version (and gnomad2, and rhythmbox-plugins).
You can then reinstall these package.

note : the Karmic version of libmtp make Rhythmbox crashing when it tries to connect my player using the MTP library.

[meow (accessdeniedno)]

How exactly do i install the karmic version of libmtp while using 10.04 final version?

[/dev/null (arndt-stedler)]

same in amd64 Version of Lucid...
see attachment...

[meow (accessdeniedno)]

So is the only solution at the moment to use ubuntu 9.10 instead of 10.04? How annoying.

[Kevin C. (kedoc)]

No. You can use Lucid.

First : you have to uninstall libmtp8 from Synpatic. It will also uninstall gnomad2 and Rhythmbox-plugins. You have to note packages that are also uninstalled.

Then you install the libmtp8 package from Karmic. You can find it there : http://packages.ubuntu.com/karmic/libmtp8

Finaly, in Synaptic, you have to block the version on libmtp8 (so it will not be updated again to the Lucid version), you can do that from the Package menu, and to reinstall gnomad2 and Rhythmbox-plugins, and eventually other packages uninstalled during the first step.

[meow (accessdeniedno)]

Ok ive did most of what you said above and now gnomad2 works again. One thing i couldn't do was block libmtp8 from being downloaded again over synaptic-not sure what what you meant here... I did find this update in the update manager (see attachment)-is this what you meant not to be downloaded again?

[Kevin C. (kedoc)]

To lock the version, you have to follow these steps for example : http://www.ubuntugeek.com/how-to-lock-package-versions-from-synaptic-package-manager.html

After that, the update manager will not propose you to update libmtp8 anymore.

[meow (accessdeniedno)]

Thanks its all working now. One last thing though-wont using karmic's version of libmtp8 mean that this will only be good till karmic is still current for another 12 months or so..what will i do when karmic is phased out?

[frenchy82 (cartes)]

meow :As you affected this bug to gnomad2, maybe you should affect it too libmtp

[Sonny (aadityabhatia)]

Shouldn't this bug be filed under libmtp8 package instead, since apparently that's the source of the problem. Using libmtp8 from karmic is a workaround, not a solution.

At this time on an up to date Lucid installation,
When MTP device is plugged in and mounted automatically:
$ gnomad2
Device 0 (VID=04e8 and PID=507d) is a Samsung YP-U3.
Queried Samsung YP-U3
Segmentation fault

Upon unmounting:
$ gnomad2
Device 0 (VID=04e8 and PID=507d) is a Samsung YP-U3.
Queried Samsung YP-U3
Bus error

[Ben Trice (v-launchpad-heroinc-org)]

I reverted to the karmic libmtp, but I still received the error. Are there any additional libs I need to revert as well?

I'm attempting to connect a Creative Zen Vision:W player which worked flawlessly within Karmic.

[ssuuddoo (ssuuddoo)]

here the same problem. Gnomad2 works well, but when inserting the player into USB, it crashes with the "Segmentation fault" debug.
pitty seing BAD upgrades of the system.
thnx 4 a solution, will use it on my old machine with the karmic installed.

No longer available in Maverick.
Closing.

[rafar (pseudocuenta)]

Using libmtp8 package from karmic solved the problem for me too.
I'm using Trisquel 4.0 which is bassed in Ubuntu 10.04 (lucid) on an amd 64 bit architecture. My player is a Zen Vision M.
