Install not allowed as another job is still in progress Security updates deployments to Servers
Having an issue with a ConfigMgr client not installing updates No errors just showing
“Install not allow as another job is still in progress” or
“Security updates preparing for installation”
Even after the reboot, machine policy reset, no resolution
There are no errors in the log files UpdateDeployment.log except showing the messages saying "Install not allow as another job is still in progress"
Steps to be followed
Kindly use SCCM Client Center to Repair WMI its more effective
SCCM Client Center to "Delete root\ccm" (button under Repair WMI) to delete the CCM Namespace from WMI. These steps worked and the SCCM service (SMS Agent Host) came back online, software updates scan took place and assignments started to apply. Updates began to download and apply as normal.
