ERROR: Could not connect to lockdownd, error code -8

Hello team,

I am using Appium 1.5.2 and i am occasionally getting “ERROR: Could not connect to lockdownd, error code -8” when i use below commands. Note we are running test in CI so it constantly runs.

ideviceinfo | grep UniqueDeviceID
idevicepair validate

And when it appium tries to run I get below error
Could not connect to lockdownd. Exiting.
An unknown server-side error occurred while processing the command. Original error: Bad app: /Users/xxx/build/xxx.ipa. App paths need to be absolute, or relative to the appium server install dir, or a URL to compressed file, or a special app name.

Although it has worked before, so i doubt it might be code bug, But if someone could give insight that will be helpful.


anyone who can help?

What version of Mac OS are you running? This issue began for me when I updated to El Capitan 10.11.6 yesterday. Running ideviceinstaller as sudo works, so I’d bet it is due to a security fix in a dependency of ideviceinstaller. Try running these as sudo and confirm. thx.
