我无法在“系统设置”中打开“软件和更新”配置窗口。从终端打开“系统设置”并单击“软件和更新”后,我能做的最好的理解是以下输出:

执行时发生相同的错误software-properties-gtk
(因为AFAIK,它是一个且相同)。
Software Updater一直存在一些类似的问题,并且经常因以下错误而崩溃:

总体而言,Python和GTK似乎到处都在呕吐,但我不知道如何解决它...
还有其他各种相关问题,例如无法从“软件中心”安装软件包,或者由于尝试在启动时进行更新而导致的各种崩溃。
我已经尝试过重新安装软件中心,但是没有运气,而且我害怕尝试这种解决方案,因为评论中的人说这是一个坏主意。在其他地方都找不到答案后,我来到了这里。
编辑:
有趣的是,我遇到了另一个与中的错误非常相似的错误nvidia-settings
。尝试保存xorg.conf设置时,错误输出如下所示。
max@Maxattax-Ubuntu:~$ sudo nvidia-settings ** Message: PRIME: No offloading required. Abort
** Message: PRIME: is it supported? no
Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found

后来,当尝试更新时pip
,我发现此错误:
max@Maxattax-Ubuntu:~$ sudo pip install --upgrade pip
The directory '/home/max/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
dbus
是罪魁祸首。非常感谢,几个月来我一直遇到这个问题,终于解决了!我感激不尽!
