Language Support Is Incomplete dialog must show package list to install

[Murz]

When Ubuntu have missing language packages, it shows in tray System Notification Helper message with text "Language support is incomplete, additional packages are required".

But when user do one simple mouse click on this notification - Ubuntu immediately asks user password with "Authentication Required" popup window, without describing what is planned to do, which packages are missing and will be installed.

After typing password - user will not see any useful info too - only small window with unnamed progress bar and standard text phrases.

After process finished - there are also zero useful info, only that process is finished.

Please show more information about this process, before ask user password!

Very useful info will be:

- How this missed packages are detected?

- Why those packages are missed?

- What packages will planned to install/upgrade (package names, versions)?

- Total size of planned downloads.

And after process is finished, there are no useful info too (screehshot is attached), only the text:

> Package successfully installed.

So the main user question is which packages are installed?

Thanks for your report!

What you say makes sense IMO, even if I don't think it would be appropriate to include all that info. But a list of suggested packages would indeed be motivated.

I think that this notification feature is really a Kubuntu specific thing, even if it probably makes use of the language-selector-common package to find the missing packages. I added the KDE Base Runtime project to the bug report.

Another thought is that if bug #1294858 get fixed (more specifically the suggestion in comment #3), there would be fewer cases when this language support notification would show up.

Status changed to 'Confirmed' because the bug affects multiple users.

I've also observed this behavior on Kubuntu 20.04.

This command appears to fix the issue: sudo apt install $(check-language-support)
