We're unable to answer Kali questions here -- we might (with some editing to clarify what you want) be able to help you restore your system to what you had before attempting to add Kali packages.

The instructions for Katoolin are very clear: Add the repo, install software, DO NOT UPDATE/UPGRADE, remove the repo.

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.
