So this occurs whenever I try to use “ujust rebase-helper” and then follow the prompts (it doesn’t matter which I choose, any of them result in the same error):

“error: Creating importer: Failed to invoke skopeo proxy method OpenImage: remote error: cryptographic signature verification failed: invalid signature when validating ASN.1 encoded signature”

I even tried (following along with the documentation) using “rpm-ostree rebase” and I get the same exact error. I am new to using Bluefin but am a pretty experienced Linux user and I’ve been trying to figure this out on my own for days now but I am at a loss. Thanks! (And if I’ve left anything out my apologies just please let me know what I need to do.)

We were rotating our cosign keypairs this morning, which is the method that we use to sign our images. During this process I made a critical error which has resulted in forcing you to take manual steps to migrate to our newly signed images. All existing Universal Blue image…

Then after that’s sorted the rebase helper should work.

Thank you! I will make sure to pay closer attention to those announcements from now on!
