Public bug reported: ---Problem Description--- Ubuntu 17.04 Guided - use entire disk and set up LVM and Guided - use entire disk and set up encrypted LVM does not create separate partition for /boot and so fails to complete the installation.
Comment 3 Looking into the logs ,this error will come if someone is using some external media (ex :USB stick ).Suppose it is /dev/sda and our hard disk is /dev/sdb .. then installation should occur on /dev/sdb, but it is trying to install on /dev/sda.. so workaround is to remove external media and continue. But, here they are doing virtual dvd install on LPAR.
