(mblock:26755): Pango-ERROR **: 10:17:25.473: Harfbuzz version too old (1.2.7)


Hello everybody!

I am trying to install mblock in Ubuntu 20.04 and the following error message appears:

A JavaScript error occurred in the main process
Uncaught Exception:

I have not found the libary Pango for Ubuntu 20.04

Thanks in advance
