初级OS提供“存储库没有发布文件”。错误

Question

我在运行Ubuntu仿生海狸。我试图在Ubuntu上下载pantheon桌面环境，但是它没有工作，所以我放弃了。现在，当我尝试从终端下载主题或其他东西时，我会得到一个提到初级操作系统的错误代码，尽管我正在下载的内容与初级或万神殿无关。下面是终端机上的内容：

jacob@jacob-MacBookPro:~$ sudo apt-add-repository ppa:tista/adapta -y
…                                          
E: The repository 'http://ppa.launchpad.net/elementary-os/testing/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.

Answer 1

根据PPA页面(初等/测试和小学/小学-每日调整)，他们没有发布18.04LTS(仿生海狸)的软件包。

因此，您应该从系统中删除这些PPA，并从它们中安装包：

sudo apt-get install ppa-purge
sudo ppa-purge ppa:elementary-os/testing
sudo ppa-purge ppa:mpstark/elementary-tweaks-daily
