mock chroot yum 出错

shpchp

我在 64-bit 的 CentOS5 里 mock 了一个 32-bit 的 chroot jail.
然后通过这个命令安装了 yum:
/usr/sbin/mock-helper yum --installroot /var/lib/mock/centos-5-i386/root install yum
(是这样装吧？)
然后运行 mock chroot yum list, 出现下列错误：

1. 
   
2. $ mock chroot yum list
   
3. init
   
4. ending
   
5. done
   
6. Non-zero return value 1 on executing /usr/sbin/mock-helper chroot /var/lib/mock/centos-5-i386/root /sbin/runuser - root -c "yum list"
   
7.
