Searching for apt.kitware.com brings me immediately to a detailed instruction page on how to add this PPA. In point 4, I see you need to install software from them that ensures that their keyring stays up to date as they regularly rotate their keys. Your message happens to indicate that the key is not correct, and thus Ubuntu refuses to work with the PPA. Make sure you update the key and keep it updated as per the instructions of the repository.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
