This question already has an answer here:
I am currently using ubuntu 12.10 i386. I was disappointed as it was unable to install any software , get update or upgrade. In a question in askubuntu, I was told to install ubuntu 14.04.And i am currently downloading the ubuntu gnome 14.04 desktop amd 64 via transmission client. I've used windows for long and i know i can't upgrade from a 32 bit to 64 bit. The ubuntu that i use now is 32 bit 12.10 so can i upgrade directly to ubuntu 14.04 from ubuntu or do i have to clean install it? If i can upgrade from this without losing files, please tell me how?
