codedeploy-agent randomly fails to install on AL2023 (can't create transaction lock on /var/lib/rpm/.rpm.lock)

Hi!

I'm installing codedeploy-agent at the very end of my user_data content:

wget https://aws-codedeploy-eu-west-1.s3.eu-west-1.amazonaws.com/latest/install; chmod +x ./install; ./install auto

However this fails from time to time on my amazon linux 2023 instance:

Inizia dallo script di installazione scaricato e dal relativo punto di ingresso per l’installazione dei pacchetti, quindi riproduci il comando durante l’esecuzione di user-data di Amazon Linux 2023. Analizza il fallimento del blocco della transazione DNF/RPM mostrato nei log; il lavoro è completo quando l’installazione intermittente non viene più interrotta dall’errore di blocco dovuto a una risorsa non disponibile.
