![elementaryOS 无法通过 PPA 安装应用程序](https://linux22.com/image/1426379/elementaryOS%20%E6%97%A0%E6%B3%95%E9%80%9A%E8%BF%87%20PPA%20%E5%AE%89%E8%A3%85%E5%BA%94%E7%94%A8%E7%A8%8B%E5%BA%8F.png)
从标题您可能已经看出来,我是 Linux 环境方面的完全新手。
尝试弄清楚如何使用 安装应用程序sudo apt-get install
。我已经能够安装一些应用程序,但最近开始失败。
例如我想安装 elementary-tweaks,但错误消息都是一样的E: Unable to locate package elementary-tweaks
我思考我知道如果我添加 PPA,我应该访问与该 PPA 关联的软件包。
因此,我尝试删除以前的 PPA(正如本网站上的一些答案所见),并添加以下内容:https://code.launchpad.net/~versable/+archive/ubuntu/elementary-update后面跟着一个sudo apt-get update
。
我也尝试过sudo apt-get -f install
PPA 清除等等……
但错误信息仍然存在。
错误信息:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package elementary-tweaks
有人能帮我指出一下,我遗漏了什么吗?还有,类似情况的可能解决方案是什么?
谢谢!
答案1
这应该适用于任何 Elementary OS,这是添加 ppa 的正确方法
sudo apt-add-repository ppa:versable/elementary-update
sudo apt-get update
sudo apt-get install elementary-tweaks
所以..如果这不起作用那么用错误更新Q
答案2
确保您在主目录中。只需关闭终端并打开一个新的终端窗口。
通过https://launchpad.net/elementary-tweaks:
sudo add-apt-repository ppa:mpstark/elementary-tweaks-daily && sudo apt-get update && sudo apt-get install elementary-tweaks
答案3
备份你的/etc/apt/sources.list先归档
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
编辑你的/etc/apt/sources.list
sudo nano /etc/apt/sources.list
复制粘贴以下内容和节省 /etc/apt/sources.list文件
更新这易于
sudo apt update
尝试再次安装您的应用。例如:
sudo apt install snapd
