No information given when installation blocked by an open package manager

[jeremypw]

I have searched open and closed issues for duplicates.

Describe the bug

If you start the installation of a language or the completion of an installation, and a package manager such as Synaptic is open, then the progress bar does not move but no information is given as to why no progress is being made.

Platform Information

Hera 5.1.4 daily

I'm using the latest released daily version

Additional context

AppCenter gives a message "waiting for package manager lock" under similar circumstances, which is not ideal but better.
