答案1
sudo apt-get -f install
这应该下载/安装所有未满足的依赖项。
答案2
我使用不同的无线连接让软件中心正常工作。路由器距离我的电脑约 15 英尺，现在一切正常。
答案3
我最近遇到了类似的问题，并使用 Synaptic 包管理器修复了它。它有一个“修复损坏的包”功能，可让您跟踪损坏的包并重新安装它们。此问题通常是由第三方存储库引起的。
答案4
转到“软件源”> Ubuntu 软件选项卡 > 下载自 > 更改为“其他”> 选择最佳服务器。让它更新，然后选择服务器并关闭。它将再次更新。等待 1-2 分钟。
打开终端并sudo apt-get update && sudo apt-get upgrade
