Hi again, One step further with the Ubuntu Startup Disk Creator: I finally found that bug 1325801 https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1325801 is fixed now with some tweaks by Yu Ning. But there is another bug, that stopped me, when I tested it. I was trying to flash Lubuntu 15.04 desktop 32-bit into a pendrive from an installed Ubuntu 14.04.2 LTS 64-bit system. After some testing Yu Ning told me "I guess you are burning the i386 ISO on an amd64 host machine? This was a blind spot in previous patch for vivid, it assumes host arch == target arch." In other words, you can only create pendrives with 64-bit systems from a 64-bit system or pendrives with 32-bit systems from a 32-bit system. I am able to create a Lubuntu 15.04 desktop 64-bit pendrive from that Ubuntu 14.04.2 LTS 64-bit system. Persistence works. Maybe someone wants to try to create a Lubuntu 15.04 desktop 32-bit pendrive from a Lubuntu 14.04.2 LTS 32-bit system. In that case, please apply Yu Ning's tweaks that you find in comment # 124.
