Issue Unable to install or update Plesk components: There are no products for your operating system | Update operation was locked by another update process

[Fritz MichaelG]

Today I noticed that our Plesk instance is suffering from this problem. In my case it says

There are no products for your operating system
( 'Ubuntu' 'Linux' '16.04' 'x86_64' ) available
 from the selected source.

That article then directs me to this one on how to install updates for Plesk. However, the first option (via the GUI) doesn't really work because of the former problem. And when trying to run

plesk installer update

via SSH, I only get the following output:

~ # plesk installer update

BUSY: Update operation was locked by another update process.
exit status 1

How could I get the Plesk updates to run again?
