应用程序“软件和更新”无响应

我似乎无法在单击“软件和更新”应用程序后显示它。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？

我曾尝试过这个答案：“软件更新程序”和“软件和更新”不起作用，但没有效果。

我也有同样的信息Ubuntu 18.04 software-properties-gtk 因 org.freedesktop.DBus.Error.ServiceUnknown 而失败。我使用 Synaptic 重新安装了该软件包python3-size，正如本文中提到的那样回答但无济于事。

我也曾尝试过清除并重新安装，software-properties-gtk正如提到的那样这里但无济于事。

更新1：

我想知道setuptools.py版本 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 升级了此版本。我刚刚发现这个 GitHub 问题“setuptools 50 中断 pip 安装“这是 22 小时前提出的。我已经卸载它了，但无济于事。

更新 2：journalctl -e在终端中 使用cmd，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，系统中安装了 python 包“requests_unixsocket”（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

我尝试过显式导入requests_unixsocket。成功了。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

答案1

python3-six我在 Ubuntu 20.04 上遇到了这个问题。我尝试了建议重新安装和的帖子python3-certifi，但这些对我不起作用。然而，在我重新安装和software-properties-gtk之后，它又开始为我工作了。所以，总结一下我运行的命令：python3-requestspython3-idna

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

我又重新开始做生意了。

答案2

Ubuntu 20.10 上也存在同样的问题...我查看了 dbus 消息：

sudo systemctl status dbus.service

看到这一行：

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

所以我重新安装了 chardet：

sudo apt install --reinstall python3-chardet

然后又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。
