Well, not really completely, because in many cases the list of system packages to be removed shown by that dialog (often veeeery long and containing lots of system packages) is directly caused by the VERY problem this thread is about, i.e. setting ssu re to an incorrect release version. Which not only just adds to the user’s confusion, but often convinces the user to interrupt the update and try to manually remove those system packages “requested for removal”, ending up with a total mess. There are lots of stories about it on this forum, also very recent ones, encountered by people during 4.6.0.11 / 12 update.
That’s why I thought it would be useful to remind about it here.
