Server Upgrade Ubuntu Bionic 18.04 to Focal 20.04

It's time again. The LTS version of Ubuntu Server 18.04 Bionic receives a system upgrade to LTS 20.04 Focal Fossa. There is no reason to upgrade yet. 18.04 is an LTS version and therefore it will continue to be supplied with system and security updates. In principle, a productive system should not be upgraded prior 20.04.1 version, as a number of bugs will still be fixed by then. This version usually appears about 3 months after publication of 20.04, most probably around mid-July. You can also see this as soon as you try to update:

Root Galaxy S8 with Samsung Firmware, TWRP and Magisk

Why rooting a mobile?

Because it is better. A lot of software available for standard computers is not possible to install because you are just on the user level. Imagine you would be using Ubuntu or Windows and would'nt have the administrator level. With root you may install system relevant software, read system data out of your phone, read logs, install adaway, firewalls or other tools or even install a complete custom firmware.

Is it possible to update the stock firmware after a root?

A clear yes and no. What doesn't work is an OTA update. System updates are simply not possible via OTA, since we have a rooted, custom system. But there is a way to update the phone without losing data. What you need is a rooted Galaxy S8 Exynos SMG950F mobile, a PC and the original charging cable.
