我改变了网络模式，使用“私有网络”，然后就可以上网了。

For the record: if you are in a Python shell, try to start a new one.I know the question is not about this, but it is the only top hit from google for this error. The original reason of the issue is still not clear as curlfrom command line downloaded the same URL with no problem, and I had no networking issue in any other application at the same time. I did ip link set <ifname> down/up, nmcli con down/up wiredwith no success. I added some of the domains to /etc/hosts, this once hasn't resolved the problem, but later at an other domain it worked. Here is a minimal example for easy testing:
作为记录：如果您在Python shell 中，请尝试开始一个新的。我知道问题与此无关，但它是 google 对此错误的唯一热门。问题的最初原因仍然不清楚，因为curl从命令行下载了相同的 URL 没有问题，同时我在任何其他应用程序中都没有网络问题。我做了ip link set <ifname> down/up，nmcli con down/up wired没有成功。我将一些域添加到/etc/hosts，这一次还没有解决问题，但后来在另一个域中它起作用了。这是一个易于测试的最小示例：
import pycurl
import io
s = io.BytesIO()
c = pycurl.Curl()
c.setopt(pycurl.FOLLOWLOCATION, 1)
c.setopt(pycurl.VERBOSE, 1)
c.setopt(pycurl.WRITEFUNCTION, s.write)
c.setopt(pycurl.URL, 'http://speedtest.ftp.otenet.gr/files/test100k.db')
c.perform()
s.seek(0)
print('Downloaded %u bytes.' % len(s.getvalue()))
