How do I fix 404 error when updating package lists? [duplicate]

  • 772

I'm running Ubuntu 18.04 LTS, and I can't install from new PPA's. It gives me a 404 error every time I try to update the package lists.

curtice@linuxloverpc:~$ sudo apt update

Reading package lists... Done
E: The repository 'http://ppa.launchpad.net/gnome-shell-extensions/ppa/ubuntu bionic 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 did not re-enable repositories after a distro upgrade, I did not incorrectly type the repo name, and the repository obviously exists at http://ppa.launchpad.net/gnome-shell-extensions/ppa/ubuntu/

How do I fix this?

launchpad updates ppa apt 18.04

    The apt-get update in your question states that gnome-shell-extensions/ppa does not have packages for Ubuntu 18.04 LTS Bionic Beaver.

    You should simply disable this repository with 

    sudo add-apt-repository -r ppa:gnome-shell-extensions/ppa

    And then continue to use apt as usual.
