How Much Size Required to Write Xubuntu ISO into USB?
I have a 4 GB USB stick and I am going to write the Xubuntu iso file into it. Will 4 GB be enough?
XFCE 20.04 Iso has 1.74 GB, so your stick is large enough.
Since the answer to this question is so obvious, I'd like to mention, that I am referring to an USB-Stick that is used to install it on a hardware.
If you want to install Xubuntu on an USB stick (not recommended but possible), then you should have at least 8GB.
