I tried to install 6.0 kernel and I just blindly followed the tutorial, so I broke my system and it now every time I try to update it shows me this error

W: GPG error: https://ppa.launchpadcontent.net/tuxinvader/jammy-mainline/ubuntu jammy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3844A6C1C6FD1056

@nb52er As `apt-key` is deprecated and on the way out, I wouldn't advise new users to use it. If the OP wanted to keep the repository, they could [add a keyring](https://itsfoss.com/apt-key-deprecated/) for example in `/usr/share/keyrings/` and have the repository refer to that. But as far as I understand, the OP just wants to get rid of the repo.

Look for the entry for this repository in the directory /etc/apt. Maybe it was added to the main source file /etc/apt/sources, maybe it was added as an individual file in the directory /etc/apt/sources.d. The entry should look similar to

deb https://ppa.launchpadcontent.net/tuxinvader/jammy-mainline/ubuntu jammy main 
deb-src https://ppa.launchpadcontent.net/tuxinvader/jammy-mainline/ubuntu jammy main

Remove those lines and reload your local package information with apt update.

@jifitailu The entry could be in the main list `/etc/apt/sources`, or in a separate file in the directory `/etc/apt/sources.list.d`. Please look in both places.

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.
