Instructions to fetch correct Ubuntu Focal 20.04 and not 20.04.5

[omac777]

The build instructions indicate to use ubuntu 20.04, but when you attempt to go there on the ubuntu web site, it redirects you to an updated version of 20.04.5 which causes more build issues. Don't use that. https://releases.ubuntu.com/20.04/ubuntu-20.04.5-desktop-amd64.iso

You need to use the older original 20.04 version. Also disable and package upgrades and only install the original packages pinned to that 20.04 release. https://old-releases.ubuntu.com/releases/20.04/ubuntu-20.04-desktop-amd64.iso

If you don't use the correct ubuntu 20.04 version, you will experience issues like this:

I disabled all ubuntu focal 20.04 repo package upgrades view the above picture for details. This ensures we build with the exact same packages as the starfive-tech team did.

I built with focal 20.04 following the instructions very carefully. It took 93 minutes on an octacore amd phenomx8 with an oscoo sata ssd.

It seems to have succeeded please have a look at this log(expires in 30days). https://easyupload.io/tdzlzg I would upload these on github but my log file exceed upload max.

None of these appeared in the work after the build. Perhaps there are errors in the build output above. It's not easy to get these build steps right.
