I have an old PowerBook which has been happily running Ubuntu Server for a few months. Now I want to repartition the hard drive and install Ubuntu Client, while keeping my existing installation intact.  When I first installed Ubuntu, I chose to erase the entire hard drive and use it as an encrypted LVM. Now, the installer seems to recognize the partitions on the drive, but it never prompts me for the password to the LVM.  How do I make room for another installation alongside my current one?

It says it's playing, my friend (on PS4) says he can hear it, but I don't. All other audio is fine, I can hear the game audio fine, even if I have a world that's only me: it still doesn't produce jukebox sounds. It visually shows that it's playing (the notes come out of the jukebox) but there is no music. I play on Pocket Edition. Can someone help me resolve this issue?
