Ubuntu 12.04 中的更新管理器每次都会冻结

当。。。的时候安装更新在更新管理器中按下按钮，更新管理器冻结。

解释该问题的屏幕截图

更新和升级并未解决问题。

我收到以下错误信息：

答案1

你的 python 包中的权限可能不起作用，请使用以下命令更改其权限-

sudo chown -R $USER /usr/local/lib/python2.7/dist-packages/

-用你的登录名替换 USER，如果不起作用，请检查输出 -

/usr/lib/ubuntu-sso-client/ubuntu-sso-login

如果它抛出任何错误ImportError: No module named pkg_resources

那么这背后的原因可能是我的 Python 环境中的安装工具包已被删除。要解决这个问题，请使用以下脚本-

curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py | python

希望它能够起作用。

答案2

尝试运行以下命令作为替代：

sudo apt-get update
sudo apt-get upgrade

这将为您运行更新，也许运行更新后您的更新管理器就会起作用。
