How do I install Ubuntu to a USB key?
I use a USB drive to boot Ubuntu and when I download my preferred language it isn't kept for me to the next time I boot Ubuntu, so every time that I boot Ubuntu, I need to download my preferred language again. Is there any way to preserve my language and other applications that I downloaded at the last boot to the next time I boot Ubuntu from my USB driver?
Thanks in advance!!
