I have a feeling you truncated the first output because it doesn't actually remove a native libglib2.0-0 but libglib2.0-0:i386 only?

Since you did not go ahead with the removal of libglib2.0-0 anyway, the packages did not end up becoming auto-removable, and hence `sudo apt autoremove` did not remove anything.

[Moshe Caspi (mcaspi12)]

I truncated the first output because I didn't see a reason to put the whole list.

I don't see a reason to print the autoremove packages at the beginning *in order not to confuse the user* like it happened to me, or in other words my suggestion is as follows:

Never print the autoremove packages at the beginning.
Answer=n: Still don't print the list of packages.
Answer=y: Print the autoremove packages after the user's answer.

[Julian Andres Klode (juliank)]

Indeed, it also doesn't fit well with the new 3.0 UI, so my plan was to actually move the messaging until the very end, after all packages have been successfully installed.

We can't exactly print it after the Y/n prompt directly because then hundreds of lines will zoom by and you don't see it, but as the final lines of program output it will be visible easily.
