Hi! I am updating my software on a regular base, after I had to rebuild my system from a Time Machine backup, something is wrong. Every time I update e.g. Libre Office, Firefox etc., it fails. All I do is to open the DMG file and move the app into the applications folder. I am asked for password and then the message The operation cant be completed because some items had to be skipped. For each item, choose File > Get Info, make sure Locked is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again. appears. As it seems, the created folder (e.g. /Application/Firefox.app) is empty. As a workaround I can delete the application before by moving it into the trash and then install the new version. I have no idea why this does not work, but maybe someone can give me some hints!
