我目前正在运行 Xubuntu 12.04 64 位。我注意到我无法打开软件中心或更新管理器。
当我尝试打开更新管理器时，它报告说a problem occurred while checking for updates。
启动软件中心时，会出现一条错误消息，告诉我
Failed to execute command "/usr/bin/software-center %u".
Failed to execute child process "/usr/bin/software-center" (No such file or directory)
运行 sudo apt-get upgrade 会发现更多问题

我真的在这里迷路了，任何帮助都将不胜感激。
提前感谢任何能帮助我的人
答案1
尝试 sudo apt-get -f install。如果它显示相同的错误，则意味着下载的软件包有问题。您必须安装另一个 ppa，用有缺陷的软件包替换稳定的软件包。因此在终端中输入以下内容
sudo apt-get 删除 python-软件属性软件中心软件属性通用软件属性 gtk
然后 sudo apt-get autoclean 然后 sudo apt-get autoremove。尝试确定您是否安装了不受信任的 ppa。如果您觉得自己没有做错任何事，请使用以下命令重新安装它们
sudo apt-get 安装 python-软件属性软件中心软件属性通用软件属性 gtk
看看问题是否仍然存在
答案2
sudo apt-get update然后尝试执行sudo apt-get -f install，如果问题仍然存在，请检查是否添加了任何不受信任的 PPA。
如果有，您可以通过执行sudo apt-get install ppa-purge来删除它们sudo ppa-purge [ppa link here]。删除后，您可以继续再次输入前两个命令。
