I have downloaded the mBlock 4.0.0 to my Ubuntu MATE 20.04.3 LTS using commands below:

sudo apt-get update
sudo apt-get install libgconf-2-4

cd ~/Downloads
wget -c https://github.com/Makeblock-official/mBlock/releases/download/V4.0.0-Linux/mBlock-4.0.0-linux-4.0.0.tar.gz
tar -xf mBlock-4.0.0-linux-4.0.0.tar.gz

On launch it shows the following message:

cd ~/Downloads/mBlock
./mblock

$ ./mblock
/home/mate/Downloads/mBlock/resources/tools/arduino
app listening on port 7070!

(mblock:7529): Pango-ERROR **: 22:27:16.382: Harfbuzz version too old (1.2.7)

The same happens with deb-package as follows:

cd ~/Downloads
wget -c http://mblockapp.oss-cn-hongkong.aliyuncs.com/mBlock4.0/mBlock_4.0.4_amd64.deb
sudo apt install ./mBlock_4.0.4_amd64.deb

I got the following errors:

$ /opt/makeblock/mBlock/mblock

I cannot install mblock locally on ubuntu 20.04

#!/bin/bash wget -O mblock.tar.gz https://github.com/Makeblock-official/mBlock/releases/download/V4.0.0-Linux/mBlock-4.0.0-linux-4.0.0.tar.gz tar zxvf mblock.tar.gz rm mblock.tar.gz mv mBlock $HOME cd $HOME cd mBlock ./mblock

With the above script the following error appears:

I have tried with the next script to: (debian package) ``

!/bin/bash

wget -O mblock.deb http://mblockapp.oss-cn-hongkong.aliyuncs.com/mBlock4.0/mBlock_4.0.4_amd64.deb
sudo dpkg -i mblock.deb``

With the above script the following error appears:

It looks they are NOT maintaining this any more.

the chip on CyberPi is an ESP32
the software mBlock is based on Scratch
what's more, mBlock is in JS but there is ONLY download for Windows and Mac (https://mblock.makeblock.com/en-us/download/mlink/) .
mLink2 is NOT well supported under Linux as well, at least, the version of mlink on github is ONLY 1.4, NOT 2.0.

I would really like to recommend we DON'T use mBlock under Linux. At least for now.
