Comment 6 for bug 628657

The effects of this bug became more annoying with recent update-manager versions.

Starting with Ubuntu 13.04, update-manager (Software Updater) was changed so that package names are no longer shown in the list. Only a one-line summary is shown, but sometimes that gives no clue as to what the package actually is; e.g. the summary could be something like "Transitional dummy package".

In order to show package names, you have to click Technical description, then on the Changes tab. As you click on each item in the list, you have to wait for the changelog to display, which takes ages and maxes out the CPU for longer changelogs (e.g. for new kernel versions). [Since 13.04 was only released recently however, currently most changelogs are quite short. Later in the cycle as changelogs get longer, that this will become more of a problem.]
