I was able to reproduce this issue on a virtual KVM instance by creating one singe primary partition, adding it as a physical volume, adding it to a volume group, and then creating one logical volume spanning all free extents.
At this point starting partman fails. Then I ran a simple mkfs.ext4 on the before completely blank logical volume. At this point starting partman is succesful, and I was able to get past the partitioning step and into the "installing base system" step (by which time I exited the installer). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/729394 Title: partman fails to load during install on LVM systems -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
