软件中心崩溃已尝试卸载并重新安装

软件中心崩溃。我正在运行 Ubuntu 12.04。已经尝试卸载并重新安装软件中心。这是我收到的错误:

在此先感谢您的帮助。

答案1

我本来想说“ sudo?”(但我认为软件中心可以自行使用 sudo……)

但这个错误是怎么回事

 SystemError: E:Opening /etc/apt/sources.list - ifstream::ifstream (13: Permission denied)

您的 /etc/apt/sources.list 是否不可读?您是否做了一些更改软件源的操作?除非软件中心因其他原因退出,否则这可能是问题所在。这实际上不是“崩溃”,或者 中有什么dmesg问题/var/log/syslog/

答案2

这些错误似乎是由于software-center缓存中的错误引起的。

删除缓存并重试。为此,请导航至缓存文件夹 -

cd ~/.cache

删除软件中心缓存文件夹 -

rm -r software-center
