我想把我的sendmail升级
我原先sendmail的版本是: sendmail-8.12.8-4
我查了一下现在sendmail的最高版本是sendmail-8.13.1-2
于是我开始升级了
sendmail-devel-8.13.1-2
sendmail-cf-8.13.1-2
sendmail-doc-8.13.1-2
这些都成功了可是到sendmail-8.13.1-2就出毛病了,问题是这样的:
warning: sendmail-8.13.1-2.i386.rpm: V3 DSA signature: NOKEY, key ID 4f2a6fd2
error: Failed dependencies:
libc.so.6(GLIBC_2.3.4) is needed by sendmail-8.13.1-2
libdb-4.2.so is needed by sendmail-8.13.1-2
liblber-2.2.so.7 is needed by sendmail-8.13.1-2
libldap-2.2.so.7 is needed by sendmail-8.13.1-2
setup >= 2.5.31-1 is needed by sendmail-8.13.1-2
我升级用的命令是 rpm -Uvh sendmail-8.13.1-2 为什么会出现这样的问题,怎样解决,求求大家帮帮我!!!!

出现这个问题的原因是：
新版本的sendmail-8.13.1-2需要下面这些安装包
1. libc.so.6(GLIBC_2.3.4)
2. libdb-4.2.so
3. liblber-2.2.so.7
4. libldap-2.2.so.7
5. setup >= 2.5.31-1
你得去下载这些包，安装完这些包后，再安装sendmail-8.13.1-2
