Invalid signature

OS Name/Version: Ubuntu 20.04.6

Product Name/Version: AMP Instance Manager v2.4.6.4

Problem Description: Basically, after an apt update, I get an error and cannot upgrade the instance manager.

Here is the error:

Err:15 https://repo.cubecoders.com debian/ InRelease
  The following signatures were invalid: EXPKEYSIG 33FB60CD1A773489 Michael Biggins <admin@cubecoders.com>

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://repo.cubecoders.com debian/ InRelease: The following signatures were invalid: EXPKEYSIG 33FB60CD1A773489 Michael Biggins <admin@cubecoders.com>
W: Failed to fetch https://repo.cubecoders.com/debian/InRelease  The following signatures were invalid: EXPKEYSIG 33FB60CD1A773489 Michael Biggins <admin@cubecoders.com>
W: Some index files failed to download. They have been ignored, or old ones used instead.

Steps to reproduce:

  • Run apt update

Actions taken to resolve so far: None. I am fairly new to gpg keys and signing and I have no idea how to fix this.

And if you don’t have Discord, this is the post:

Important notice for Debian/Ubuntu/Similar users - The signing key used to verify the integrity of the CubeCoders repo has been extended.

You can fetch the latest version of the key by running the following as root:

wget -O /usr/share/keyrings/repo.cubecoders.com.gpg https://repo.cubecoders.com/archive.key

This will download the latest version of the key which expires now in 2028.

Thanks Mike! I didn’t see this when I googled this forum came up first thank you so much!

I tried the command but the problems still excists. Is there anything I am missing? (I’m on Debian 11)

Run getamp addRepo instead (as root)

Then clean up the old source in sources.list after
