今天在安裝一個插件curl，安裝失敗了。報錯內容如下：
root@R619AC_co-router:/tmp/tmp# opkg install curl Installing curl (7.68.0-1) to root...

其中最重要的就一句話
check_data_file_clashes: Package libmbedtls12 wants to install file /usr/lib/libmbedtls.so.2.16.3 But that file is already provided by package * libmbedtls
有一個需要安裝一個依賴包libmbedtls12 但是已經存在的依賴包 libmbedtls 已經有這個文件了，查了一下版本號是2.16.3-2
而新的版本號看文件也是2.16.3。但是實際安裝完了顯示是2.16.4-1。
為什么是這樣？我想想估計是我安裝的openwrt的版本比較低，導致內置集成libmbedtls 版本，與官方軟件源里不一致。而在線安裝curl是是根據官方源最新的版本。
這時候，我只能卸載原來的libmbedtls 包，手工安裝libmbedtls12包才可以繼續安裝。這樣也會導致原有的依賴libmbedtls的軟件無法運行，所以底包很重要
