every time i do apt update i got this error message
E: The repository 'https://ppa.launchpadcontent.net/brightbox/ruby-ng/ubuntu jammy 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.
i already tried to do
sudo ppa-purge ppa:brightbox/rubg-ng and still got problem
also already tried reinstalling and something similiar to ppa, launchpad,and ruby but i think i don't get the right package in this case. i also see the sources.list in apt folder, there is not something similiar to ppa, launchpad,and ruby
