解决 gpg: Can't check signature: public key not found      
     
    repo init 的时候出现错误
    object 12fd10c20115046dcd2fbe468a45e566f38ffbc9
    type commit
    tag v1.12.7
    tagger Conley Owens <cco3@android.com> 1381959964 -0700

    repo 1.12.7

    gpg: Signature made 2013年10月17日 星期四 05时46分04秒 CST using RSA key ID 692B382C
    gpg: Can't check signature: public key not found
    error: could not verify the tag 'v1.12.7'

    解决:
    【1】curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

    【2】chmod a+x ~/bin/repo


    另外,用repo sync 抓取 android source code 的时候,会经常出现一些错误导致 repo sync 中断,每次都要手动开始。

    可以在一个脚本里写如下的命令,来自动取重复:

    repo sync
    while [ $? -ne 0 ]
    do
        repo sync
    done
