Ok I actually made it work. Not sure if this still belongs here, but might as well inform others how I fixed it. Maybe it will help you as well.
Although I had never connected the iPhone to my PC before, I needed to reset the trust settings to get the dialogue option to "trust this device" on the iPhone. The procedure is quite simple. Go to Settings > General >> Reset >> Reset Location and Privacy. It is also explained here: https://www.guidingtech.com/fix-iphone-trust-this-computer-not-showing- up-issue/ By the way, I then still could not paste files on the iPhone. This might be an Xubuntu specific issue, but I had to install iFuse first.
