Had the same problem installing in a VM. A "swapon -s" shows that there are two swap spaces created by zram (part of the RAM gets compressed and and used like swap space but with higher priority than "real" swap space).
For the installer it really seems that there is swap space enabled in the system so it does what it should in this case: Warn about that and cancel the installation. So no bug in my eyes. With that information it's really easy to perform the installation anyway: Open a terminal and type "sudo /etc/init.d/zram-config stop". After that there are no swap spaces provided by zram anymore and the installer does it's job without complaining/aborting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241833 Title: Lubuntu 13.10 installation with full disk encryption fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1241833/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
