-\section{Problems and Resolution}
-The first repository update failed with a missing OpenPGP signing-key error.
-Victor downloaded Docker's key again, set its file permissions, checked the
-\texttt{Signed-By} path, and repeated the update. Installation then succeeded.
-The exact cause of the initial missing-key state was not established.
-
-The Ubuntu image selected was 26.04 rather than the initially planned 24.04.
-The actual OS and architecture were checked before using Docker's matching
-\texttt{resolute} repository. A Compute Optimizer access message appeared in
-the instance summary; it did not prevent the EC2 deployment and no extra
-permissions were added for that optional feature.
