如何在更新包列表时修复404错误？

Question

我正在运行Ubuntu18.04LTS，我无法从新的PPA安装。每次我试图更新软件包列表时，它都会给我一个404错误。

curtice@linuxloverpc:~$ sudo apt update
[sudo] password for curtice:

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.

在发行版升级之后，我没有重新启用存储库，我没有错误地键入回购名称，而且存储库显然存在于http://ppa.launchpad.net/gnome-shell-extensions/ppa/ubuntu/。

我该怎么解决这个问题？

Answer 1

您的问题中的apt-get update声明gnome-shell-extensions/ppa没有Ubuntu18.04LTS仿生海狸的包。

应该简单地禁用这个存储库

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

然后继续像往常一样使用apt。
