This article describes a workaround when Juniper Security Direct On-Prem fails to download the IDP Signature.

Unable to manually download IDP signature in Security Director On-Prem, even though the download job says Success.

We get the following error in the job when the user tries to update/install the signature on the device:

"Error encountered while Install Signature for device:

Signature Installation failed, could not find matched version."

Any new user who installs Juniper Security Director (On-Prem) may encounter this issue, where they are unable to download Signatures from the UI.

As a Workaround, the user must download and upload the sigpack for the first time into the Juniper Security Director (On-Prem) setup, and then they can use the download sigpack option.

This is a known issue due to some backend changes from the signature team.
