Hi.
On the daily build download page is the following warning for Ubuntu MATE 16.04:
Warning: This image is oversized (which is a bug)
and will not fit onto a 1GB USB stick. However, you may still test it
using a DVD, a larger USB drive, or a virtual machine.
That is only a problem for the .iso size or also can cause trouble after installation? For example there are too much packages in that .iso or the wrong or something like that.
Or how is it possible to have an oversized image?
Hi,
Ubuntu used to use 700 MB ISO files and now they use 1.1 GB or higher sized files, you can safely continue as long as you use a USB of 2GB or more in size, or of course a burnable DVD disk!. 
Hi.
Thanks for the answer.
But why are they using this big files now and call it a bug? So I understand it the way, that there is the normal amount of packages in the iso, but the size is bigger because of a bug.
Or which packages are new to Ubuntu and use 400MB? And why then its a bug?
Hi Tom,
you will have to address that question to the Ubuntu devs.
@Tom Almost all alpha releases of Ubuntu images are oversized, due to several issues. This will be corrected as we near the official release.
You can install 16.04, but remember, it is an alpha release and not meant to be installed on production machines. Please report bugs you encounter.
If you want stability you can install 14.04 LTS or 15.10.
Ok. Thanks for the answers.
