Bug Description

I downloaded the 11.04 desktop i386 iso, put it on a usb drive so i could it install it on my netbook, but couldnt even get past the install screen, because it says i need 4.4GB to install ubuntu 11.04. The problem is that my hard drive is only 4GB large, a common size in netbooks. I have run installers for ubuntu 10.10, 10.04, 9.10 and 9.04 netbook editions on my netbook and never had a problem before. I notice that 11.04 has netbook and desktop editions combined into a single ISO, so maybe that is why the error happened in 11.04 and not before.

Also, I notice that the install footprint of 10.10 is around 2.1GB, so it shouldnt be a problem running 11.04 unless they truly added 2GB of junk to the OS. The problem is I just can't get past the installer.

If 10.10's installation medium was only 2.1GB, for both the desktop and netbook edition, then 4.4GB isn't that much difference once you combine them. It would only be ~0.2GB difference to combine 10.10 in the same way.

As far as your problem, I have no clue as to why it would be wanting to install all 4.4GB of media if there are 2 separate versions on the disk.

I think this is a problem with the installer. I'm not sure how to assign this bug to the installer. Anyone know?

I confirm the same behavior on an EeePc 4G; the forward button is greyed out.

According to Ubuntu Installer Team - if you have a bug in the installer found on the "desktop" or "live" CD (the graphical installer), then please file that against the "ubiquity" package.

I've got a work around...

Run the live CD, press alt+f2 and type:

gksu gedit /usr/lib/ubiquity/plugins/ubi-prepare.py

Then on line 310, change "min_disk_size = size * 2" to "min_disk_size = size * 1.4"

Then run then Ubuntu installer.

Confirm that Nathan's workaround works on a mini 9 with a 4 gig SSD.

I created a new bug under the correct package - ubiquity because i could not figure out how to move this bug to the correct package. I marked this as a duplicate. All future discussion should happen under bug:

Thanks for the workaround Nathan, i will try that, but hopefully this bug will be fixed in ubiquity.
