I tried to upgrade to 11.10 today. When I clicked the "Upgrade Now" button in the Update Manager, it told me I needed something like 4 GB available on my / partition and I only have a little less than 2. That's fine, I have other partitions with plenty of space on them. I decided to download a .iso, mount it and do a CD upgrade.
I added the ISO file successfully using "apt-cdrom add" and tried again, using do-release-upgrade. I got back the following errors and 11.10 refused to install:
I am using the 64-bit version of Ubuntu 11.04 currently. I downloaded ubuntu-11.10-desktop-amd64.iso from ubuntu.com. Does anyone have any idea for what's going wrong or what I can do to upgrade my current system?
