The sixth attempt succeeded: I installed Ubuntu 14.04.2 LTS, made it up to date, and into that system I installed Unetbootin via the developer's ppa instead of from the Ubuntu repository. https://launchpad.net/~gezakovacs/+archive/ubuntu/ppa sudo add-apt-repository ppa:gezakovacs/ppa sudo apt-get update sudo apt-get install unetbootin and Unetbootin could make a good installer pendrive with vivid-desktop-i386.iso Persistence file size 512 MB (I did not want to wait while a huge file was created). Persistence works. I installed Lubuntu twice into an SSD with the option 'Something else'. The installer system in the USB pendrive was not damaged after the installation. -o- Summary: 1. mkusb just works, because it is independent of changes between versions of the Ubuntu flavours. 2. Unetbootin works, when installed via the developer's ppa. It will bring the version 603-1~trusty1 now. (The version in Ubuntu repositories is not up to date.)
