我在 Kubuntu 18.04 上无法连接到我所在机构的 wifi。我使用的笔记本电脑在使用 Windows 10 时可以正常连接。我也可以在 Android 设备上使用我的用户名和密码进行连接。Android 设置是 EAP = PEAP、阶段 2 =“无”且无 CA 证书。
但在 Linux 上它不起作用。我查看了很多其他帖子，但都没有成功。到目前为止，我尝试编辑以/etc/NetworkManager/system-connections/删除system-ca-cert=true这个帖子但这一行一开始就不存在，我尝试按照第一个答案中所述修改文件，但我的配置文件看起来与他的非常不同。我尝试进行适当的更改，但没有建立任何连接。我也尝试查看这个帖子但无法让事情正常运转。
当我尝试连接时，以下是信息：

我尝试查找“原因 3”，但几乎找不到解决方案。我尝试在设置文件中提供我的用户名和密码，但也没有用。它似乎试图使用 MSCHAPV2。没有 none 的设置。我也尝试了 MD5 和 GTC。这些都没有用。我尝试在网站上找到的设置文件中输入 none，但没有用，而且在其他地方有人说这样做无论如何都是无效的设置。
我不知道还有什么其他的想法。它适用于 Android。能否打印出它用于连接的设置？
（我用 XXXX 代替可能的识别信息，但它似乎与我网站日志中的实际名称正确匹配）
任何帮助都会受到感谢，哪怕只是在正确方向上的推动。谢谢！
