OnTAP Upgrades in the Simulator

TMADOCTHOMAS — Tue, 05 May 2026 18:16:11 GMT

Hello,

I've upgraded the OnTAP Simulator numerous times in the past, but I'm running across an issue when trying to go from 9.14.1 to 9.15.1. Any ideas why I keep getting this error? I unblocked the files before running them, and tried re-downloading the file. I know the file is not corrupt as I used the same one on some production clusters.

Download complete.

Listing package contents.

Decompressing package contents.

Verifying package signature.

Install failed. Failed to verify the signatures of the image. The image might have been corrupted. Replace the image, and then try the command again.

@TMADOCTHOMAS

There are two KBs reported and both with Bugs reported which provide steps to fix this. Take a look at these KBs;

Thank you very much @pereirath . Unfortunately, CC-Mode was already set to false on our simulator so there was nothing to change in our case.

I should note this occurs when running the initial "system node image update" command to simply upload the tgz file for the upgrade.

No I checked space and there is enough free space.
