Itunes app Update

[andrema2]

Ok, so I have a bunch of apps that needs to be updated on iTunes. First, almost all applications were updated already on my iPhone or my iPad. I have synchronized both devices with iTunes, but the apps didn't sync. Why is that ?

Nevertheless, I tried to update the apps using iTunes, but it fails with error 8008.

Does anyone knows how to solve both problems ?

Thanks in advance

Devices with iOS 9.0.2 or later installed don't synchronise apps with iTunes. If all of your devices have iOS 9.0.2 or later installed, then you can safely delete all of the apps in your iTunes library.

If you worry about losing one app after developer pull the plug, you can remain them. Otherwise, you can delete them. However, this means it is impossible to restore your device without wifi connection anyway. (My guess)
