I need to preface this by saying I‘m also new to Linux, but I‘ve got it working I think. The instructions you and I tried to follow aren‘t brilliantly written and are a bit out of date. I took all of the security settings off my device before trying this so you may want to do the same, e.g/ No password or passcode.

Start by getting all of the required applications and packages.

 sudo apt-get install ideviceinstaller python-imobiledevice libimobiledevice-utils libimobiledevice6 libplist3 python-plist ifuse 

Connect your device and test that it‘s being recognised using idevice.

ideviceinfo

Pair your device using idevicepair.

idevicepair pair

Validate the pairing using idevicepair

idevicepair validate

Create the mount point for your device, my device was an iPod Touch.

sudo mkdir /media/iPod-touch

Give all users access to the mount point.

sudo chmod 777 /media/iPod-touch

Mount the device using the newly created mount point.

ifuse /media/iPod-touch/

Now you should be able to access your device from your file manager!
