除非我以 root 身份运行，否则软件中心不会启动。以 root 身份运行它时，出现一条有关缓存不可写的消息。我的 .cache 文件夹位于单独的驱动器上，并符号链接到我的主目录。有趣的是，此后软件中心似乎可以正常工作。我认为它在我安装 Pidgin 后就坏了。
这是我尝试以自己的身份运行软件中心时的终端输出

软件中心似乎当我使用 sudo 运行时，至少它可以启动。但它让我有点紧张，我希望能够使用启动器...
我尝试过的事情：
sudo chown winobes ~/.cache
sudo chown winobes ~/.cache/software-center
sudo apt-get install --reinstall software-center
感谢您的帮助和见解:)
答案1
噢！
sudo chown winobes ~/.cache
显然只是改变了符号链接的所有者....
sudo chown winobes /mnt/data/.cache
解决了我的问题。
