ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
    Following is the list of potential problems / advisories:

    Fetcher failure for URL: 'https://www.example/'. URL https://www.example/ doesn't work.
    Please ensure your host's network is configured correctly,
    or set BB_NO_NETWORK = "1" to disable network access if
    all required sources are on local disk.

解决方法：

在local.conf中增加以下内容，三选一，可自己按理解修改，个人使用跳过检查连接

#检查连接使用谷歌
#check connectivity using google
CONNECTIVITY_CHECK_URIS = "https://www.google/"

#跳过检查连接
#skip connectivity checks
CONNECTIVITY_CHECK_URIS = ""

#检查连接使用百度
#skip connectivity checks
CONNECTIVITY_CHECK_URIS = "www.baidu"

按提示set BB_NO_NETWORK = "1" to disable network access，是行不通的，尽量配置local.conf
