Steps to reproduce:

  • i type sudo su -
  • i tpye bash <(wget -qO- getamp.sh)
  • i set my admin login data
  • no to docker
  • yes to java/minecraft
  • yes to steam
  • no to https

Actions taken to resolve so far:
I tried removing the amp directory aswell as the keyring for amp from the usr/keyring directory. My etc/apt/keyrings directory is empty.
I’m a first time ubuntu server user. I found several threads online talking about the keyrings but it seemed like they were mostly in the etc/apt/keyrings directory for other people.

Of course i tired restarting the system.

I also tried to newly update the system giving me a new error.

I also read that it might be a bad ip6 connection, but ip6 is disabled.

Fix your webmin repo. Nothing to do with AMP
