I went to Ubuntu's website and looked for the .img file for my Raspberry Pi 400. I can only find the desktop version of 20.10, which is not a LTS and not the one I want. Where can I find the 20.04.1 DESKTOP (not server or core) to flash? I have Balena Etcher for MacOS and I am going to flash my 512GB SanDisk MicroSD Card. I can only find the server and core builds of 20.04.1, but not the desktop.
Also, will this OS work fine on the 400? I tried it on my 3B and the desktop environment takes all the resources on 1GB of RAM. I know the Gnome DE (what Ubuntu uses) takes a lot of resources, hopefully it will work fine as my main PC on my Pi 400. I have high hopes for this OS, as I am ready to move on from Ubuntu MATE and want to use normal Ubuntu.
