I was waiting for official instructions on ubuntu.com for installing Ubuntu LTS on my Raspberry Pi 4 (4GB edition). Since a few days there is a new site/downloads with official support for the Raspberry Pi 4 (Ubuntu Server 18.04.3 LTS and Ubuntu Server 19.10; 64- and 32-bit) and appropriate instructions.
I tried to install Ubuntu Server 18.04.3 LTS (64-bit) on a 64GB SanDisk Ultra Class 10 micro SD card as instructed after the download:
- What you’ll need... (including "A Raspberry Pi 2, 3, or 4")
- Flash Ubuntu onto your microSD card... (using Windows with Win32DiskImager)
- Boot Ubuntu Server...
- Login to your Pi...
Unfortunately Step 3 is not working: Only the red LED on my Raspberry lights up constantly (using 3A/15W USB-C-power-supply). I waited over 10 minutes - to not avail.
Setup: Only a VGA-Display is connected to the HDMI0-Port via microHDMI -> HDMI and HDMI -> VGA adapters. Raspbian Buster is working without any problems.
Thanks for your support!
