1 我的Debian5 安装不上语言包，有依赖关系？大家帮我看一下需要安装什么？2 红旗Linux无法挂载光驱？

问题1的提示：warning: fonts-chinese-3.02-12.el5.noarch.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

gcc，make，autoconf，我都装了还是不行
问题2的错误提示：mount：you must specify the filesystem type  没有加参数之前的错误提示
mount -t ext3 /dev/cdrom /mnt/cdrom
mount ：no medium found on /dev/sr0  加上参数之后的错误提示
