Error while trying to install application in iOS 8

[ph1ps]

Hey,

I'm running a Linux machine and installed ideviceinstaller. The device is an iPhone 5S on iOS 8. But when I try to run the command gives me this error code: Could not connect to lockdownd. Exiting.

Any idea how I can fix this?

Did you accept the trust dialog on the device?
Any idea of what "Linux machine" you have and which versions you installed?

[ph1ps]

Well it's a RPI so I think its Debian and yes I accepted the trust dialog.

I have the same question with Ubuntu 14.04 64bit.
Did you solve this problem.

[FunkyM]

Please post the output of a debug run (use the -d option).

iPhone 4S, iOS 8.1.2

# idevicebackup -d backup /root/test/

Same problem here, iPhone 5S, iOS 8.1

koenig@mtddios00:~/idevice/ideviceinstaller$ /usr/local/bin/ideviceinfo --udid a5582936801832a48f4224fc4a2844cccbf49251 --xml
ERROR: Could not connect to lockdownd, error code -2

Edit: I could handle this error by using the newest version. After this tapping on 'trust' in the trust dialog worked and the error didn't show again/

Just built all the idevice libs from github versions, on Ubuntu 14.04 64-bit I get this problem as well.

Output of syslog when I plug in the iPad is below. Simultaneously, on the device it shows "Trust this computer" and on the computer it shows a GUI stating "Unable to mount iPad Air - Unhandled Lockdown error (-20)" (presumably it tried to auto-mount something.)

It doesn't matter whether I tap trust on the device, no further commands work. I tried restarting usbmuxd with usbmuxd --force-exit, but still get the lockdown message after.

Any ideas?

Huh, I was just able to install successfully by running usbmuxd in the foreground:

usbmuxd --force-exit
sudo usbmuxd -f -v

[15:18:13.800][3] usbmuxd v1.1.1 starting up
[15:18:13.800][4] Creating socket
[15:18:13.800][4] Initializing USB
...

Full output here.

And in another terminal:

ideviceinstaller -d -i Main.ipa

@jcward exactly the same works for me :) Thanks

[jcward]

FYI, still get the unhandled lockdown error, the sudo workaround still works, iOS 8.4.
