When performing a Snow Agent update via the Snow Inventory Admin Console to upgrade the Snow Inventory Java Scanner, the update may fail, and the following error messages appear in the Snow Agent log:
Line 3425: 2025-04-23T10:54:41-4:00; ERROR; snowagent; update\UpdateManager.cpp; `anonymous namespace'::ValidateExecutableSignatures; File sijs.jar does not have a valid signature
Line 3429: 2025-04-23T10:54:41-4:00; ERROR; snowagent; update\UpdateIntent.cpp; Update::UpdateIntent::Execute; General error (255): Failed to validate signatures
This issue occurs when the sijs.jar file is included in the agent update without its corresponding SIGN file. Snow Inventory requires that certain files, such as Snow-provided JAR files, be accompanied by a SIGN file to verify their authenticity.
To resolve this issue, ensure that when including any Snow-provided JAR files (for example, sijs.jar) or the xMetering2 file (for macOS) as support files in the agent update, you also include the accompanying SIGN file.
These files can typically be found in the following directory on the Snow Inventory Master Server:
C:\ProgramData\SnowSoftware\Inventory\Resources\Agent\
Note that the snowagent binary also requires a SIGN file; however, this is automatically added when selecting the agent version in the update wizard.
Custom JAR files cannot be included in the agent update, as they cannot be signed with a key trusted by Snow.
For more details on creating a new agent update and including support files, refer to Create a new agent update.
