iPhone tethering no longer working under natty

[Jiehan Zheng]

The network manager can recognize my iPhone 3GS and offered a new menu item for the iPhone. It automatically tries to connect to the Internet via the iPhone once I plug it in, but after I updated to natty it always fails.

A few required outputs:

jiehan@jiehan-laptop:/$ lsb_release -rd
Description: Ubuntu Natty (development branch)
Release: 11.04

jiehan@jiehan-laptop:/$ apt-cache policy ipheth-utils
ipheth-utils:
  Installed: 1.0-3build1
  Candidate: 1.0-3build1
  Version table:
 *** 1.0-3build1 0
        500 http://archive.ubuntu.com/ubuntu/ natty/universe amd64 Packages
        100 /var/lib/dpkg/status

Please let me know if there's anything missing or I did anything wrong. Thank you.

Seems to be a problem related to DHCP.

jiehan: is this still broken in the Ubuntu 11.04 beta1 that came out today?

[Jiehan Zheng (jiehanzheng)]

paul: Thank you. I updated just now and unfortunately it is still not working. The syslog output was the same and it end up with this:

NetworkManager[544]: <info> Activation (eth1) Stage 5 of 5 (IP Configure Commit) failed (no IP configuration found)

[Mathieu Trudel-Lapierre (cyphermox)]

This isn't an issue in NetworkManager, but somewhere in ipheth or the iPhone itself, which does not yield a DHCP address:

Please verify your configuration, in case usb tethering on the iPhone was disabled.

Jiehan Zheng, thank you for reporting this and helping make Ubuntu better. Natty reached EOL on October 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please plug the USB iphone in, unplug all other USB devices, execute the following at a terminal and post the results to this report:
lsusb

As well, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.
