Linux下奇怪库破坏导致一大堆程序启动失败一例
给开发板装了一个postgre，可是启动的时候问题多多

提示5432可能被占用，但是仔细看了看端口也没被占用啊

看看log，然后试试看ping 127.0.0.1，what's the fuck
pi@BLASTN2 ~ $ ping localhost
PING localhost (127.0.0.1) 56(84) bytes of data.

解决方案：
保存之后，
$ sudo ifconfig eth0 down
$ sudo ifconfig eth0 up
或者干脆直接
$ sudo reboot
再来ping一次，可以ping通。

可是奇葩的是obconf失败了，所有窗口都没标题栏了。。。一看提示

dafuq？啥玩意儿，file一下结果居然是ISO-8859-TEXT，我操，说好的库呢，干脆重装一次得了，
$ sudo apt-get -f install obconf
$ sudo apt-get install obconf --reinstall
$ sudo reboot
ok, done。其实猜测是因为之前用了错的opera源导致的，这个一般都是32、64以及arm的库弄混了的原因。待会儿清个源。
然后，虽然这个没问题了，但是libcrypt.so.11还是有同样的问题，浏览器起不了，reinstall libgcrypt11-dev无果，拷贝debug下的更是不行，直接报segment fault。

只好祭出大杀器。
附上so文件，用自带的传输功能传的，信得过就下吧，自己改名回去：

注意，如果你缺这个文件，连wget curl都是启动不了的，如果是远程机器，自求多福如果开了啥samba sftp ftp之类的还可以一拼= =，物理机器就靠u盘吧。
修完了真是开心啊，postgre？去你的，不装了- -
