I did not see any errors or mention of breakages.
Control Centre still does not open. I don't know how likely this is to become a problem in the future. Are there other ways to access the various settings normally accessed via Control Centre? I don't specifically need Control Centre for anything at this moment. I notice that in some other distros there is nothing specifically called "control centre." BTW, there are also problems with Software Manager in that most of the categories listed do not bring up any of the programs available in that category. Is there a way to "clean up" the installation, by getting rid of possible unnecessary files.
