应用程序“软件和更新”没有响应

  • 772

单击“软件和更新”应用程序后，我似乎无法显示它。我不知道为什么。它的图标出现在快捷方式中。激活此应用程序的终端命令是什么？

我试过这个答案：“软件更新程序”和“软件和更新”不起作用，但它不起作用。

$ uname -a

$ software-properties-gtk

我也有与 Ubuntu 18.04 software-properties-gtk 相同的 msgs失败 org.freedesktop.DBus.Error.ServiceUnknown。我使用 Synaptic 重新安装此答案python3-size中提到的软件包，但无济于事。

我也尝试过这里software-properties-gtk提到的清除和重新安装，但无济于事。

更新1：

我想知道setuptools.pyver 50.0 是否破坏了软件-属性-gtk 的连接？我知道系统昨天从版本 42.0.2 升级了这个。我刚刚发现22 小时前提出的这个 GitHub 问题“ setuptools 50 breaks pip installation ”。我已经卸载了它，但没有用。

更新 2：在终端中 使用journalctl -ecmd，我发现了这个错误消息：

Oct 04 08:22:14 Prime dbus-daemon[1303]: [system] Activating service name='com.ubuntu.SoftwareProperties' requested by ':1.157' (uid=1000 pid=10808 comm="/usr/bin/python3 /usr/bin/soft

Oct 04 08:22:14 Prime com.ubuntu.SoftwareProperties[1303]: NameError: name 'requests_unixsocket' is not defined

此外，python 包“requests_unixsocket”安装在系统中（见下文）。因此我不明白错误消息NameError: name 'requests_unixsocket' is not defined：

$ pip list | grep requests
requests                2.24.0
requests-unixsocket     0.1.5

$ pip3 list | grep requests

我试图明确导入 requests_unixsocket 。有用。见下文。

Python 3.6.9 (default, Jul 17 2020, 12:50:27) 
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license()" for more information.
>>> import requests_unixsocket
>>> a = requests_unixsocket.Session()
>>> a
<requests_unixsocket.Session object at 0x7fb103952470>

我不明白为什么我可以导入包但/usr/lib/python3/dist-packages/softwareproperties/LivepatchService.py看不到它。它确实存在：

$ ls /usr/lib/python3/dist-packages/ | grep request
requests_unixsocket
requests_unixsocket-0.1.5.egg-info
software-sources 18.04

  1. Best Answer

    我在 Ubuntu 20.04 上遇到了这个问题。我尝试了建议重新安装python3-sixand的帖子python3-certifi，但这些帖子对我不起作用。但是，software-properties-gtk在我重新安装python3-requests和python3-idna. 所以，总结一下我运行的命令：

    sudo apt install --reinstall python3-six python3-certifi python3-requests python3-idna
sudo apt install --reinstall software-properties-gtk
software-properties-gtk

    我又开始做生意了。

  2. Ubuntu 20.10 上的同样问题...我查看了 dbus 消息：

    sudo systemctl status dbus.service

    并看到了这一行：

    .../... com.ubuntu.SoftwareProperties[8310]: ModuleNotFoundError: No module named 'chardet'

    所以我重新安装了chardet：

    sudo apt install --reinstall python3-chardet

    并且software-properties-gtk回来了。

    日志显示：

    dbus-daemon[1130]: [system] Successfully activated service 'com.ubuntu.SoftwareProperties'

    希望能帮助到你。
