Canonical: Ubuntu Linux will support all Raspberry Pi devices
Canonical recently announced its support plan for the Raspberry Pi 4 and said it will support all Raspberry Pi devices. With the release of Ubuntu Server version 19.10, Canonical announced the official support for the Raspberry Pi 4. The Raspberry Pi 4 is powerful, but at a lower cost, allowing for consolidation of computing workloads at the edge.
In the blog, Canonical said it will work hard to provide full official support for all motherboards in the Raspberry Pi series. Canonical will provide Ubuntu Server and Ubuntu Core support for the existing and upcoming Raspberry Pi.
The Raspberry Pi 4 B comes in 1GB, 2GB, and 4GB with several different RAM options, but currently Canonical officially only supports 1GB and 2GB versions. Due to a kernel error, the official arm64 image of the 4GB RAM version does not support USB out of the box. Canonical engineers have identified kernel fixes and are currently testing them extensively. Canonical said that after the test is successfully completed, the update will be pushed in a few weeks.
