因此，我安装了带有 gnome3 的 Ubuntu 18.04，然后被 elementary OS 5.0 的漂亮外观所吸引，我按照说明安装了它。现在，我已按照以下建议清除了所有 PPA这或者这里的其他答案。但是，我在启动时以及about在 gnome UI 中看到时仍然会看到 elementary os 屏幕。
化妆品对我来说不是什么大问题，但是当我尝试从 18.04 升级到 18.10 时，我没有收到任何更新sudo do-release-upgrade -d。sudo do-release-upgrade
我该如何彻底恢复我的 gnome？或者更直接地说，我该如何升级到 18.10？

答案1
从 LTS 升级到非 LTS 版本是个坏主意。您需要等待 20.04 LTS，所有可能的停止点为 19.04 和 19.10。考虑继续使用 18.04 LTS。
如果您已经通过 PPA 添加了基本内容，那么您可以使用以下命令将其删除：
sudo apt-get install ppa-purge
sudo ppa-purge ppa:elementary-os/daily
sudo ppa-purge ppa:elementary-os/os-patches
sudo ppa-purge ppa:elementary-os/stable
sudo ppa-purge ppa:elementary-os/staging
sudo ppa-purge ppa:elementary-os/testing
然后重新安装 GNOME Shell
sudo apt-get install ubuntu-desktop
由于我们有输出，dpkg -l | grep -i elementary因此我可以建议两件事：
1. 清除剩余的有rc状态的包（以及剩余的配置文件）：
sudo apt-get purge $(dpkg -l | grep -i elementary | grep ^rc | awk '{print $2}')
2. 使用以下命令重新安装软件包初级来自当前存储库的版本：
sudo apt-get install --reinstall $(dpkg -l | grep -i elementary | grep ^ii | awk '{print $2}')
