Cannot find Thunderbird executable (Linux)

[qajaq49]

I recently installed Kubuntu 20.04, and one of my first tasks has been to install Thunderbird, my long-time favorite email client. This time, however, it does not show up in the Application Launcher widget (as it has done in every previous version of Kubuntu I've used since 9.04). Nor can I find an executable file.

I've tried which thunderbird, and whereis thunderbird and I've tried find / -type f -name "*thunderbird*" as root user. I can see all sorts of ancillary files, but no executable file.

Yet when I try apt-get install thunderbird I am told that the latest version is already installed.

What gives? Why is Thunderbird so well hidden? How can I find the executable file to install in my Application Launcher?

Try using apt-cache showpkg thunderbird

Can you find the thunderbird script file?

No script file showed up in any of those searches I described above. However, it finally occurred to me to use the analog of the "power-off-power-on" trick; in this case, removing and purging the package, then re-installing it. After doing that, Thunderbird showed up in the Application Launcher.

You might want to see if Synaptic is available and use that when experimenting.
In some cases it ties in with the update and application software managers.
From the description:
Synaptic is a graphical package management tool based on GTK+ and APT.
Synaptic enables you to install, upgrade and remove software packages in
a user friendly way.

Besides these basic functions the following features are provided:
* Search and filter the list of available packages
* Perform smart system upgrades
* Fix broken package dependencies
* Edit the list of used repositories (sources.list)
* Download the latest change log of a package
* Configure packages through the debconf system
* Browse all available documentation related to a package (dwww is required)
