docker openwrt openclash

在使用docker 安装完openwrt 以后,安装openclash是很可能遇到如下问题

~ # opkg install luci-app-openclash_0.44.29-beta_all.ipk

Installing luci-app-openclash (0.44.29-beta) to root...

Installing dnsmasq-full (2.85-8) to root...

Downloading https://downloads.openwrt.org/releases/21.02.2/packages/i386_pentium4/base/dnsmasq-full_2.85-8_i386_pentium4.ipk

Collected errors:

* check_data_file_clashes: Package dnsmasq-full wants to install file /etc/hotplug.d/ntp/25-dnsmasqsec

        But that file is already provided by package  * dnsmasq

这个报错是因为dnsmasq-full 与dnsmasq冲突导致

如果这时候你先卸载了dnsmasq

会出现以下问题:

root@OpenWrt:/tmp# opkg remove dnsmasq

Removing package dnsmasq from root...

Not deleting modified conffile /etc/dnsmasq.conf.

Not deleting modified conffile /etc/config/dhcp.

Configuring dnsmasq-full.

Collected errors:

* resolve_conffiles: Existing conffile /etc/config/dhcp is different from the conffile in the new package. The new conffile will be placed at /etc/config/dhcp-opkg.

总结:

安装与卸载应该同步进行

opkg remove dnsmasq && opkg install dnsmasq-full

如果还是不慎卸载，你还有办法挽救：首先，dnsmasq 承担的是解析域名的角色，所以只需要想办法绕过域名解析就可以了

编辑 /etc/opkg/distfeeds.conf，将 downloads.openwrt.org 替换为解析到的 IP 即可。

例如：在网络正常的机器上，执行 ping 到一个源：

ping downloads.openwrt.org

PING downloads.openwrt.org (xxx.xxx.xxx.xxx):56 data bytes#Or USTC mirrorsping mirrors.ustc.edu.cn

PING mirrors.ustc.edu.cn (xxx.xxx.xxx.xxx):56 data bytes

ping 会显示解析出的 IP，将其记下并替换即可
