error: %preun(xxx) scriptlet failed, exit status 1

问题原因： 卸载过程中的chkconfig --del mysoft需要使用到/sbin/insserv相关工具，缺失工具时，语句执行不成功，因此返回error: %preun错误。

修改办法： 卸载时检测系统上是否安装了insserv工具（机器上的版本为insserv-compat-0.1-2.15.noarch.rpm）,没有则提示“Uninstall failed, you need install 'insserv' tools before retry.”，并返回一个错误码-1（即255），使后续的其它卸载操作不再进行。

     对于暂时无法找到此工具的用户，可以执行如下两条命令进行卸载，两条命令按先后执行。
     rpm -e --noscripts mytest-mysoft
     rpm -e  mytest-mysoft

更正后没有安装工具的卸载报错提示： linux-m8wg:~ # rpm -e mytest-mysoft Uninstall failed, you need install 'insserv' tools before retry. error: %preun(mytest-mysoft-1.2.2008-sles.15sp1.x86_64) scriptlet failed, exit status 255 error: mytest-mysoft-1.2.2008-sles.15sp1.x86_64: erase failed
