As we try to install the downloaded IDP signature on an SRX340 cluster we received the below error:
 

error: Security Package installation disabled temporarily due to invalid license.

Meanwhile the show system license display:

• On the Primary Node, enter configuration mode and disable the IDP process:

srx# set system processes idp-policy disable

srx# deactivate security idp

srx# commit

• On both nodes, delete the directory from the shell (as root). This will allow you to rebuild the IDP directory:

srx> start shell

% rm -r /var/db/idpd

% rm -r /var/db/appid

% rm -r /var/db/ai_cache

• After verifying that the IDP directory is deleted from both nodes, reboot both nodes:

% cli

srx> request system reboot

• The reboot of the device will automatically remake the IDP folder/directory. At this point, re-enable the IDP process (idpd) on the Primary Node. You had previously disabled IDP configuration under the security hierarchy.

srx> edit

srx# delete system processes idp-policy disable

srx# commit

• Use the following commands to download and reinstall the IDP package on the Primary node:

srx> request security idp security-package download full-update

srx> request security idp security-package download status

srx> request security idp security-package install

srx> request security idp security-package install status

Continue checking the status. You should see the successful installation message once it is done.

• Once the status shows a success message, re-activate the IDP configuration on the Primary node:

srx# activate security idp

srx# commit
