I am using Ubuntu 22.10 on a Digital Ocean image. I try to run this command:

sudo apt-add-repository -y ppa:brightbox/ruby-ng

but I get these specific error messages in output;

Err:3 http://old-releases.ubuntu.com/ubuntu kinetic-security Release                                                         
  404  Not Found [IP: 185.125.190.37 80]
Err:8 https://ppa.launchpadcontent.net/brightbox/ruby-ng/ubuntu kinetic Release
  404  Not Found [IP: 185.125.190.52 443]

E: The repository 'http://old-releases.ubuntu.com/ubuntu kinetic-security Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: The repository 'https://ppa.launchpadcontent.net/brightbox/ruby-ng/ubuntu kinetic Release' does not have a Release file.

Besides, I tried apt update and got the same errors above.

"kinetic" (22.10) was just released so it makes no sense to have an "old-releases" repository, it doesn't exist. You need to correct that either by editing or removing. The PPA exists but hasn't been updated since 2021 therefore it has nothing for your release. Remove it.

Does this answer your question? [What can I do if a repository/PPA does not have a Release file?](https://askubuntu.com/questions/866901/what-can-i-do-if-a-repository-ppa-does-not-have-a-release-file)

PPAs are 3rd party software sources so all security checks are on you to perform before adding.. A quick glance & I can see the PPA you added hasn't had any attention since 2020 (20.04) and provides no support for later release; did you check? It has nothing helpful for 22.10 and the lack of maintenance should have *felt* a security risk to you (https://launchpad.net/~brightbox/+archive/ubuntu/ruby-ng)

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.
