Openwrt opkg update wget return 8

這一個月發現用opkg update 個openwrt 有以下error,

- 部機可以上到網, 所以應該唔係network 問題
- 可以ping 到www.openwrt.org 所以應該唔係dns 問題
(因為我曾懷疑是OpenDNS block 左個connection)

root@OpenWrt:~# opkg update

爬了一會文發現原本的version (attitude adjustment) 已經不再更新，而package 更加移走了。所以opkg update 不能更新。


故我的openwrt 要做sysupgrade.. 今次去download 返個sysupgrade image

https://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/

找回原本個router 的image version ... 不要弄錯...

再在Luci 做sysupgrade 即可。

不過記得要抄走自己的script 先... 我唔記左.. 乜都冇... 首先要改返咁個opkg.conf

cat /etc/opkg.conf

dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists

更新要點：
1. Privoxy 改左config 位罝 由/etc/privoxy/config 轉左去 /etc/config/privoxy
2. 若果之前keep config 應該安返d package 就可以用返，不過唔需要用好多時間。
