尝试更新应用程序时基本操作系统出现错误

我无法更新我的 basic os Hera 5.1 上的任何应用程序（通过终端或 AppCenter）

当我转到 AppCenter 尝试更新我的应用程序/系统时，显示以下错误

E: The repository 'http://ppa.launchpad.net/mpstark/elementary-tweaks-daily/ubuntu bionic Release' does not have a Release file.

我能够更新sudo apt-get upgrade以前通常使用的应用程序，但现在这样做会留下此错误，并且实际上没有任何更新

我该如何修复这个错误？

答案1

Elementary OS Hera 5.1 基于 Ubuntu 18.04 Bionic，并且出现错误的存储库没有 Bionic 的发行文件。

  1. ppa.launchpad.net/mpstark/elementary-tweaks-daily/ubuntu仅具有 Ubuntu Trusty (14.04) 和 Ubuntu Utopic 14.10 的发行文件，请参阅这里

  2. download.01.org/gfx/ubuntu/14.04/main/dists/是 Ubuntu Trusty (14.04) 的存储库

  3. ppa.launchpad.net/pinta-maintainers/pinta-stable/ubuntu有各种较旧的 Ubuntu 版本的发行文件，但没有 Bionic 的发行文件，请参阅这里

从源中删除这些存储库应该是安全的。然后运行后再次尝试更新sudo apt-get update。

答案2

首先，它表示您缺少某个公钥。找回丢失的钥匙。您可以通过以下方式执行此操作 -

gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv FFACA3F86663559C

其次是 -

gpg --export --armor FFACA3F86663559C | sudo apt-key add -

看看是否能解决您的问题。如果没有，请使用新的警告和错误编辑您的问题

现在，您还应该删除一些过时的源。打开/etc/apt/sources.list文件并通过在包含这些内容的行前面添加 a 来注释掉它们#。
