Quick upgrade to Ubuntu12.04

I can't resist the upgrade speed. The 4 m Telecom broadband, the download of the update package is slow. the scroll bar is only half a day. I know that Ubuntu12.04 has just been released, and there must be many people upgrading it, however, the update manager keeps prompting you whether to upgrade the new version or not. This is a problem. Without patience, the Upgrade Program is slowly running, and other operations are not delayed. After several things are handled, the scroll bar is still not moved, and I found Ubuntu12.04, the iso file has been downloaded. The specific download link is: http

It's really hard to hold back the upgrade speed. The 4 m Telecom broadband, the download of the update package is slow. the scroll bar will take a while. I know Ubuntu 12.04 has just been released, and there must be a lot of people upgrading it, however, the update manager keeps prompting you whether to upgrade the new version or not. This is a problem.

Without patience, the Upgrade Program is slowly running, and other operations are not delayed. After several things are handled, the scroll bar still does not work, and we can find Ubuntu 12.04, the iso file to download, the specific download link is: http://releases.ubuntu.com/12.04/ubuntu-12.04-desktop-i386.iso

Start the Virtual Machine and use thunder to download files faster. If the file size is more than MB, it will take less than five minutes to download the file. After the iso file is downloaded, check whether the file can be upgraded from iso.

Why cannot I upgrade it offline?

It is not easy to find a standard answer. I started from the official website and found the official recommendations. There are also many questions about the upgrade, and I also posted a question, ask if you can upgrade from iso to get an answer that is neither correct nor wrong.
