Can you help me? My ubuntu 22.04 is working well, but all start begins with the message: Failed to start Apply Kernel Variables

Based on earlier similar questions, ( in case of Ubuntu 16) the message is different. What should I do?

sudo systemctl status systemd-sysctl.service

Remove what you added to `/etc/sysctl.conf`, [edit] its contents into this question if unsure. It's not a shell script.

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.
