This is the first time I have a problem with Thunderbird.

Chosen solution

So the solution is:

remove the lightning add-on in Thunderbird; exit from Thunderbird; install xul-ext-lightning package with

sudo apt install xul-ext-lightning (it will pull more packages in).

restart Thunderbird.

That should work if Lightning wasn't present in the original installer, but if it was, but is not visible, the preference reset described here should also work.
