Ubuntu has "click" packages:

For everyone else (including Ubuntu):

• http://flatpak.org/

LibreOffice is now available via Flatpak:

Although there are some caveats:

Flatpak-based apps are not yet able to reach out to other applications installed on the machine (like browsers) to e.g. open URLs through them. That means that e.g. clicking on a hyperlink in a LibreOffice Writer document might not work yet.

Besides being a path to having a single Linux bundle format, there are also sandbox features that might be appealing. Might be nice to know that a VSCode extension can't modify /boot, etc.
