更新包列表时如何修复 404 错误？

Question

我正在运行 Ubuntu 18.04 LTS，但无法从新的 PPA 安装。每次我尝试更新包列表时，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.

我没有在发行版升级后重新启用存储库，我没有错误地输入存储库名称，并且存储库显然存在于http://ppa.launchpad.net/gnome-shell-extensions/ppa/ubuntu/

我该如何解决？

Answer 1

在apt-get update你的问题中指出，gnome-shell-extensions/ppa没有为Ubuntu 18.04 LTS仿生海狸包。

您应该简单地禁用此存储库

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

然后继续apt照常使用。
