OpenWrt解决【/tmp/openclash_last_version】下载失败

第一次进入openwrt里安装的openclash进行内核更新出现以下错误：

2025-04-26 14:31:16【/tmp/openclash_last_version】下载失败：【curl: (6) Could not resolve host: raw.githubusercontent.com curl: (6) Could not resolve host: raw.githubusercontent.com curl: (6) Could not resolve host: raw.githubusercontent.com】
2025-04-26 14:31:11【/tmp/clash_last_version】下载失败：【curl: (6) Could not resolve host: raw.githubusercontent.com】

解决办法：
1，SSH连接openwrt
2，测试连通性

1	ping raw.githubusercontent.com

看到结果应该如下，这是不通的，这是因为DNS污染了
ping: bad address 'raw.githubusercontent.com'
3，检查hosts

1	cat /etc/hosts

输出结果：

127.0.0.1 localhost

::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

输出以上结果说明需要添加DNS,进入DNS查询网查询raw.githubusercontent.com对应的dns，结果选择中国的
我选项的是185.199.111.133
4，编辑hosts
输入以下代码编辑hosts

1	vim /etc/hosts

在ff02::2 ip6-allrouters的下方输入以下内容

1	185.199.111.133 raw.githubusercontent.com

按esc，然后输入wq保存退出
5，再次ping连通性

1	ping raw.githubusercontent.com

假如看到64 bytes from 185.199.111.133: seq=8 ttl=55 time=134.035 ms说明DNS污染解决

以上已经解决【/tmp/openclash_last_version】下载失败的问题，再次进入Openwrt里的openclash更新插件既可正常安装了

假如出现以下错误，同样的是因为DNS污染，配置hosts可以解决

配置后的hosts

127.0.0.1 localhost

::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
185.199.111.133 raw.githubusercontent.com
104.21.80.1 api.wcc.best

其他错误

假如如下错误

2025-04-26 16:38:06 【/tmp/yaml_sub_tmp_config.yaml】下载失败：【curl: (28) Failed to connect to api.wcc.best port 443 after 30002 ms: Error curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to api.wcc.best:443 】

是因为订阅转换的问题，改一下订阅装换既可解决，假如不能，测试自建订阅装换地址，参考教程
