VM15.5安装银河麒麟V10 SP1 2303，进入桌面以后无限弹出浏览器并且访问https://capnet.elementary.io/
您已经成功联网！
您的网络现在很正常。您现在可以安全的关闭窗口，继续使用您的设备。
为什么会显示这个窗口？
当你连接到新 Wi-Fi 网络后，elementary OS 会自动检查网络连接情况。如果发现没有网络连接（例如你在咖啡厅或者其他公共场所连接公共无线热点网络），该窗口就会弹出，并显示登录页面。
一些网络可能会被误认为是无线热点网络，于是触发这个窗口，但实际上已经成功连接到网络。这种情况下，您会看到这个信息。您现在可以安全关闭窗口。
解决办法：注释掉脚本中中的语句“sudo -u “$user” –preserve-env=DISPLAY,XAUTHORITY -H xdg-open http://capnet.elementary.io 2>&1 > /dev/null”。

esac这个BUG的原因不知道，只知道这个脚本和NetworkManager进程有很密切的关系，man了一下nm-applet，大概意思是检测当前网络up/down状态的。反正nm-applet不停报错，这个脚本就不停的弹网页，很有意思的是这个脚本似乎是来自elementary OS，但又涉及到debian。
