一个奇怪的bz2问题

TaoD1013

各位老大:
  小弟今天在解压缩tar.bz2文件的时候用了网络上说的所有办法都没办法解压courier-authlib-0.58.tar.bz2 这个文件.大虾帮我看下是什么原因啊.

我的系统是FC4的.

方法1:
[root@ytest src]# tar -xjf courier-authlib-0.58.tar.bz2
bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Error exit delayed from previous errors

方法2:
[root@ytest src]# bzcat courier-authlib-0.58.tar.bz2
bzcat: courier-authlib-0.58.tar.bz2 is not a bzip2 file.

方法3:
[root@ytest src]# tar jxvf courier-authlib-0.58.tar.bz2
bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Error exit delayed from previous errors
[root@ytest src]# tar -jxvf courier-authlib-0.58.tar.bz2
bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Error exit delayed from previous errors

方法4:
[root@ytest src]# bzip2 -cd courier-authlib-0.58.tar.bz2
bzip2: courier-authlib-0.58.tar.bz2 is not a bzip2 file.

说的很明白
bzip2: courier-authlib-0.58.tar.bz2 is not a bzip2 file.
