How many times will a gnome extension happen to update and then stop working? To me a lot!
I’ll try to write a short guide to blocking individual extension updates. First I will explain how to manually install a single extension:
download the extension from the official website https://extensions.gnome.org/ (or wherever you prefer) and install it with the following command in a terminal:
gnome-extensions install [application_name]
edit the file “metadata.json” inside that dir
(with nano o whatever you prefer)
Put in the version number of the extension a much greater value than the current one (ex if 30 put 300 … you can even put the number 0 (zero) if you prefer a subsequent manual update from the site)
