The connection between Ubuntu 14.04 LTS and iOS7 has been fixed.

Ubuntu 14.04 LTS is still under development. Due to the use of the old library, it may be unable to connect to the iOS7 device, but now this problem has been fixed by developers.

Because the libimobiledevice library has not been updated for a long time and the old version does not support IiOS7, when the iOS7 device is connected to the computer, a dialog box is displayed asking whether to trust the device. After you click "trust, ubuntu does not return the correct information, so the phone cannot be connected to the computer.

The developer on Launchpad has developed a new libimobiledevice library and has passed a series of tests. However, Ubuntu has run feature freeze, therefore, you cannot add this new version of Library to the official library unless you add it to the official library.

However, before the new libimobiledevice library is added to the official library, you can still use PPA to install the library to solve the connection problem. Open the Terminal and execute the following command to install the Library:

Sudo apt-add-repository ppa: timo-jyrinki/libimobiledevice

Sudo apt-get update

Sudo apt-get upgrade

After the library is installed, some problems may occur. If "lock down error" occurs, use the following command to solve the problem:

Sudo mkdir/var/lib/lockdown

Sudo chmod 777/va7Lib/lockdowno

To restore the database to a previous version, run the following command:

Sudo apt-get install ppa-purge

Sudo ppa-purge ppa: timo-jyrinki/libimobiledevice

If the problem persists, restart your computer or log out and log on to the system again.
