I'm new to Linux and Terminals so any "obvious answers" may not appeal to me as easily.
When trying to update via `sudo apt update` I am thrown the following errors.
"The repository 'https://ppa.launchpadcontent.net/oguzhaninan/stacer/ubuntu jammy Release"
"Updating from such a repository can't be done securely, and is therefore disabled by default."
"See apt-secure(8) manpage for repository creation and user configuration details."
Does anybody body have a super simple fix? Even if it's not simple, please just explain it step by step.
Thanks in advance!
