Error unpacking rpm package upstart

Hi: I have been getting this error when it attempts to update: [2019-08-20 00:11:50 -0700] E [/usr/local/cpanel/scripts/rpmup] The "/usr/local/cpanel/scripts/rpmup" command (process 29261) reported error number 1 when it ended. I ran '/usr/local/cpanel/scripts/rpmup' this command, and this is what it reveals [CODE=rich]Running Transaction Updating : upstart-0.6.5-17.el6.x86_64 1/2 Error unpacking rpm package upstart-0.6.5-17.el6.x86_64 error: unpacking of archive failed on file /etc/dbus-1/system.d/Upstart.conf;5d Verifying : upstart-0.6.5-17.el6.x86_64 2/2 Complete! info [rpmup] Completed yum execution "--assumeyes --config /etc/yum.conf update": in 8.652 second(s).

Can you kindly give me any advice on how to bypass this or resolve it?
