我遇到了 Wifi 和以太网连接突然断开的问题。因此，我在 Google 上搜索了这个问题，发现这篇帖子是关于解决我遇到的问题我尽力按照帖子和评论来解决我的问题，但这并没有解决我的问题，然后我看到一条评论说卸载 GNOME 的网络管理器并安装 WICD 网络管理器可以解决这个问题，并且他还分享了安装 WICD 网络管理器的命令，但这些命令不起作用，因为这些命令在 Ubuntu 18.04 或更早的版本中可用。
我意识到阅读这个帖子由于 Python 2 弃用，wicd 已从存储库中删除。之后，我关注了以下帖子：这个并尝试通过下载软件包并手动安装来安装 WICD，命令如下
mkdir -p ~/Downloads/wicd
cd ~/Downloads/wicd
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/p/pygtk/python-gtk2_2.24.0-6_amd64.deb
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/p/pygtk/python-glade2_2.24.0-6_amd64.deb
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wicd/python-wicd_1.7.4+tb2-6_all.deb
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wicd/wicd-daemon_1.7.4+tb2-6_all.deb
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wicd/wicd-gtk_1.7.4+tb2-6_all.deb
sudo apt-get install ./*.deb
sudo apt-get install ./*.deb # second time for correct configuration
为了手动安装 WICD，我运行了所有命令，但最后当我运行命令时，sudo apt-get install ./*.deb终端看起来像这样
lmao@lol:~/Downloads/wicd$ sudo apt-get install ./*.deb

我不知道如何解决这个问题。
注意：我正在使用 Ubuntu 20.10。

上述错误输出意味着你需要在 Ubuntu 20.10 上手动安装更多依赖项wicd：
mkdir -p ~/Downloads/wicd
