Building Flutter Engine on Ubuntu

I use Ubuntu 20.04. When I run https://github.com/flutter/flutter/wiki/Setting-up-the-Engine-development-environment step 7
sudo ./build/install-build-deps-android.sh
ERROR: Only Ubuntu 12.04 (precise), 14.04 (trusty), 14.10 (utopic), 15.04 (vivid), 16.04 (xenial), 18.04 (bionic), and Debian (rodete and stretch) are currently supported
And the doc says:
If you're on Linux, run the following. Note: These scripts are distro- and version-specific, so are not guaranteed to work on every configuration. If they fail, you may need to find comparable packages to the ones that weren't found.
Based on the documentation, How do I know which packages are not compatible.
Maybe you can modify that install-build-deps-android.sh script and force 20.04 and try to go on the building process?

How to install pre-requisites for Hyperledger Composer on Windows10

I am following the tutorial for Hyperledger Composer. I'm trying to install the pre-requisites for the Composer as outlined here:
https://hyperledger.github.io/composer/installing/installing-prereqs.html
The instructions are only provided for Ubuntu or Mac, and I have Win10 machine with Docker 17.12.x
So I got Ubuntu 16.04 docker image, added curl. I got the prereqs-ubuntu.sh script, I login as blockchain user, and run the script, but I get this error:
#Updating package lists
-sudo apt-add-repository: command not found
Is it even possible to install Hperledger Composer on a Windows 10 machine?!
No it is not possible to install Hyperledger Composer on windows which includes the Windows Subsystem for Linux and other environments like MinGW that simulate a linux environment. This platform is not supported at this time. I recommend you use a hypervisor such as VirtualBox or if you are using Windows 10 Professional, the built in Hyper-V support to run a Linux virtual machine where you can install Hyperledger Composer. Also we recommend using ubuntu 16.04 as this is the level we test with most.

Kubernetes-Ubuntu14.04: How to install and configure kubernetes using Ubuntu 14.04

I'm new in using kubernetes and I need to know how can I install and use kubernetes with different nodes using ubuntu 14.04,
because all what I found is aroud ubuntu 16.04.
There is a huge difference between the two version concerning kubernetes.
I need to have a master and two slaves(using the same OS).
Is recommended to Work with kebernetes on ubuntu 14.4 ?
Thank you for your help.
Kubernetes makes use of systemd, which is not available in Ubuntu 14.04. While it is possible to install in Ubuntu 14.04, you would have to do some magic in order to make it work. You can find more info here: How to install latest Kubernetes in Ubuntu 14 (Thanks to Janos Lenart who shared in the comments)

How to connect to local docker?
OK, there is Search button.
But the first time it gave me default with wrong URL,
should be https://192.168.99.100:2376 (as on Windows)

If my CentOS 7.2 box has vagrant 1.7.2, can I just run the 1.8.1 rpm to get vagrant 1.8.1?

I have a CentOS 7.2 laptop. I have VirtualBox 5.0.x installed on it. Out of the box, it appears that I have Vagrant 1.7.2. Apparently this doesn't support VirtualBox 5.0.x, but it appears that version 1.8.1 does. What is the proper way to get access to 1.8.1? There is an installation rpm for 1.8.1 that I've downloaded, I can run this with "rpm", but do I have to do anything else before I do that?
Use Software Collections to get Vagrant 1.8.1 on CentOS: Vagrant 1.8 by Software Collections (the linked page contains instructions on how to do that). That will give you a build tested by the CentOS project.
As a sidenote: If you downloaded a standalone RPM package (presumably directly from the Vagrant project) and wish to install it, do it using the yum package manager, not rpm -- yum takes care of dependencies.
