Hi, thanks for the report. Can you try the below command to update the GPG key?

curl -fsSL https://artifacts.aws.cloud.mov.ai/repository/movai-applications/gpg | sudo gpg --dearmor -o /usr/share/keyrings/movai-archive-keyring.gpg

Hi @MithunKinarullathil, Thanks for the fix. It really helped me solve the issue, Can I know what exactly the command does other than updating the key and also I am curious how the issue might have occurred or got the Key corrupted ??

[MithunKinarullathil]

That's basically it, it updates the keys. I believe we had a similar issue in that the key got outdated.
