问题[pantheon](ubuntu)

我想在 Ubuntu 20.04 中试用 pantheon 桌面。我跑了：

sudo add-apt-repository ppa:elementary-os/daily
sudo add-apt-repository ppa:elementary-os/os-patches
sudo apt update
sudo apt dist-upgrade

我改变了主意，但我发现它software-properties-gtk不再起作用，所以我无法通过 UI 删除 PPA。/etc/apt/sources.list.d我在（也尝试过add-apt-repository --remove）ppa-purge中手动删除了它们

仍然 software-properties-gtk 没有工作，直到我手动修复/etc/lsb-release 并/etc/os-release用 Ubuntu 部分替换提到基本的文本。

现在大多数人似乎又开始工作了。

我的两个问题：

1. 究竟是什么造成了我的混乱（我想sudo apt dist-upgrade是罪魁祸首）以及发生了什么变化（比如/etc/lsb-release）？

2. 有没有办法（除了重新安装）彻底清理问题？（我刚刚看到文件喜欢/etc/issue并且/etc/issue.net也被改变了）

我正在尝试在 Ubuntu 上构建pantheon 基本欢迎程序，但它在构建阶段一直失败，因为它找不到accountsservice. 但是accountsservice显然已经安装了。. 我正在按照页面上给出的构建说明进行操作。

操作系统信息：

介子构建命令行：

meson build --prefix=/usr

最奇怪的部分是accountsservice已经安装到其最新版本。

另外，如果我做一个locate accountsservice

到底是怎么回事 ？为什么当它明显存在时meson找不到？accountsservice

我已经在 Ubuntu 18.04 上安装了 Pantheon 桌面环境（来自elementaryOS 的环境），现在我从 lightdm 盯着这个 DE 时遇到了问题。特别是当我在登录前从 lightdm 菜单中选择 Pantheon DE 时，输入密码然后按 enter/login，屏幕变暗，然后返回到 lightdm。

我该如何调试这个问题？如何在不运行显示管理器的情况下直接从 tty1 运行 DE，看看出了什么问题？

无论上次会话期间的状态如何。我希望每次都禁用 Wifi 和以太网以主动连接到外部。我想防止每次自动连接到网络。

解决方案应该适用于 GNOME 桌面和/或 Pantheon 桌面

使用 Ubuntu 18.04

我做了什么：

$ sudo add-apt-repository ppa:elementary-os/stable
$ sudo apt update

Ubuntu 18.04.3 Mate 尝试安装 Pantheon-Files 但出现错误：

$ sudo apt-get install -f pantheon-files

尝试过其他方式，例如 snap 或 flatpak 或 appimage，但没有运气。

我最近在我的新 Ubuntu 18.04 上安装了 pantheon-terminal，但我遇到了重叠文本的问题。

我尝试使用 dconf-editor 更改字体，但没有任何改变。

有谁可以帮助我如何改变间距或以某种方式解决它？问候！
