Sometimes it is needed to build local version of Ubuntu MATE Welcome and Software Boutique.
There are two ways to do so - building Snap locally or building deb-package locally.
Snap
To proceed one needs any Ubuntu version installed with enabled CPU virtualization in BIOS/UEFI.
Then install needed development packages:
sudo apt-get install git snapd
sudo snap install snapcraft --classic
sudo snap install multipass
And get source code of Ubuntu MATE Welcome and build and install Snap package of it:
cd ~/Downloads
git clone https://github.com/ubuntu-mate/ubuntu-mate-welcome-legacy.git
cd ubuntu-mate-welcome-legacy
snapcraft
sudo snap install ./ubuntu-mate-welcome_*.snap --dangerous --classic
Then launch Ubuntu MATE Welcome from terminal:
snap run ubuntu-mate-welcome
or from menu to do some testing.

Note: this method is preferable to run on real hardware, it will work on VM if one knows how to enable nested virtualization for multipass.
Deb
Here we need to acquire sources and then compile the package by using below commands:
sudo apt-get install git dpkg-dev debhelper python3-dev python3-polib gettext
cd ~/Downloads
git clone https://github.com/ubuntu-mate/ubuntu-mate-welcome-legacy.git
cd ubuntu-mate-welcome-legacy
dpkg-buildpackage -uc -us
Before the installation of locally compiled package it is recommended to remove already installed packages by
sudo snap remove ubuntu-mate-welcome software-boutique
sudo apt-get purge --autoremove ubuntu-mate-welcome
Then one can install locally compiled deb-package instead by
sudo apt-get install ~/Downloads/ubuntu-mate-welcome*.deb
and then launch it from GUI or from terminal.
Note: this deb-based method is compatible with x11docker, it does not need virtualization.
