  • Tag set to “amarok, iphone, permissions”
  • State changed from “new” to “open”

  It is not a known bug and it's not a behaviour that should happen.

  Please supply the following infos:

  • Distribution and Version
  • Desktop Environment in use
  • How do you mount your iPhone? iFuse/GFVS/KIO?
  • iPhone model and OS version?
  • Where and when exactly does that "unable to change permission..." dialog come up? Within Amarok or Dolphin or...?
  • Did you compile everything or installed from packages?
  • Which version you have running of usbmuxd, libimobiledevice and ifuse (if in use)?

  In general, if you are able to run "ideviceinfo", everything should work. If not, it is often some configuration issue of the system.

  • I use (k)ubuntu lucid (KDE desktop)
  • I have a 3G iPhone (FW 3.1.2 with Tweak for 3.1.3, so ideviceinfo see it as 3.1.3)
  • The error appear everytime i copy a file into the iPhone (dolphin + ifuse, Amarok)
  • I have this error with git version and package version (currently I have git compiled version) I have this:
    
  • iFuse 1.0.0
  • usbmuxd 1.0.4
  • libimobiledevice 1.0.1
  • libplist 1.3

  Thanks for the information.

  Please describe how you mount the device and into which directory.

  Also please check the syslog while you get the dialog, usbmuxd should notify about any issues.

  Also running ifuse with the "-d" debug switch shows what is going on exactly at the time things go wrong.

  My assumption is that the directory you create for the mount has wrong permissions or your user accessing it is not member of the "fuse" group.

  Amarok auto-recognize iPhone so mountpoint for it is /tmp/kde-nico/amarok/device etc etc
  With iFuse I mounted in ~/iphone (777 privileges) or /media/iphone

  ifuse -d doesent's seems to see errors and on my syslog there aren't ubmuxd notify
  My user is member of "fuse" gorup

  can be this issue related to a bad libimobiledevice configuration?

  • Milestone order changed from “0” to “0”

  I can confirm this on Kubuntu 10.4. Makes copying my entire collection (~5GB) impossible due to endless popups indicating "unable to change permissions ...". I have also tried:
  - Adding my user to the fuse group. (I wasn't on it; added it and logged out/in, still no results) - Logging into my ipod touch via ssh and setting permissions of /var/mobile/Media/ (ie sudo chmod a+w -R /var/mobile/Media/) - Uninstalling and reinstalling. I used kubuntu repo and ppa repo for newer version. Both versions show same message)

  I solved it by restoring FW (and then re-JB it ad so on)

  not it works

  Sorry, I tried your suggestion (restored factory FW) and I think it made it worse. It certainly didn't fix it. Please let me know what kind of information would be useful.

  • State changed from “open” to “hold”
  • Tag changed from “amarok, iphone, permissions” to “amarok, iphone, jailbreak, kubuntu, permissions”

  I was talking about the device's syslog which one can monitor by running "idevicesyslog" in parallel.
  If during the dialog nothing pops up there, it is cleary not a bug and rather a configuration/permission issue.

  Besides:
  a) Kubuntu has no iPhone support judging from forum reports. For whatever reason they screwed up while Ubuntu has all working fine.
  b) Again, please run "idevicesyslog" in parallel and post what error it shows during the dialog coming up.
  c) "Faking" a firmware as with 3.1.2 -> 3.1.3 is generally a bad idea. ;)

  To me this clearly sounds like you guys screwed up your device configuration during your jailbreak party so it misbehaves now...
  To further confirm this, restoring and re-JB makes it work again (as it fixes up the permissions on the device).

  Now I don't see any bug on libimobiledevice and related components here.

  @Ricardo: Could you also please supply the information I requested in my first comment? Thanks!

  I'm a little tied up until this weekend, but I will do so.

  I must stress, however, that I put on the stock firmware and did not jailbreak and still got the error. I looked upstream to find some info, and last thing I wanted to try was to put an entry for my device on /etc/fstab, since kde mounts devices and such that are not on fstab to a subdirectory under /tmp. Somewhere I read this solved someone's problem with getting the same "change permissions" error while using other software. If you know how I can add the device to my fstab (ie fstab line), I may be able to tell you if this solves the problem. Until that, I will post something over the weekend using idevicesyslog. I hope I can help you guys out best I can. Thanks for the great software.

  Please note that the whole libimobiledevice/ifuse implementation is not using device nodes or mounting similar to other storage device implementations. It is just a fuse driver with a total custom implementation.

  Thus it is not really made to be used with fstab. If you still want to set it up you would have to create a symlink in /sbin/mount.ifuse to your ifuse binary and use "ifuse" as filesystem part the fstab line. It should be able to handle the requirements of the regular mount command.
