Is there a rpm command to check .rpm package installation log

Question

当安装未能找出发生了什么情况时，是否有rpm命令来检查.rpm软件包安装日志

Answer 1

You can get all the command line help by typing, either

 rpm --help

or

 man rpm

You can use the verbosity flag vv (two v for more) during installation to know more:

 rpm -Uvvh foo.rpm --test

--test does a dry run of the installation, but doesn't write to the disk.. You can remove it to go with a real installation.
