-Troubleshooting:
-----------------
-* Upstream has a new dependency on meson version >= 0.54 and Python (3.x)
-  mako module >= 0.8.0 now, and that broke the build on Ubuntu 20.04.5.
-  So install python3-mako and update meson:
-
-    $ sudo apt install python3-mako
-
-    $ sudo add-apt-repository ppa:ubuntu-support-team/meson
-    $ sudo apt update
-    $ sudo apt install meson
