The goal: Install a regular Ubuntu Mate system on an USB stick.
What I've done so far:
1) Using an Ubuntu Mate installation USB stick. Selecting another USB stick as target using the default software provided for that, named Ubiquity. Result: Several attempts made, doesn't work. At least the final step - installing grub - fails.
2) Using a freshly installed Ubuntu Mate. Selecting a USB stick as target using the software Ubiquity that comes along with the installation. First: The software titles to install "Kubuntu" not "Ubuntu Mate". Second: It tries to unmount system partitions - the one the current system is using. Result: Doesn't work. Hangs at least after determining the current time over a network time server. The GUI just hangs, no recovery of the application possible.
So could anyone please tell me how to install a regular (not an installation) Ubuntu Mate on an USB stick? My goal is to run Ubuntu from that USB stick later.
