Either your hosts CA truststore is out of date, or you experience the result of a man in the middle attack.
It is not uncommon that companies perform “tls inspection” which can be considered as a planed man in the middle attack.

Please use the forum search with the keywords “tls inspection” and you will find plenty of topics where this has been discussed.

hello evryone. i am facing the same problem here. i am using oracle linux 9 and i just installed docker engine, when i try to pull an image or even try to run hello-world i get error :
docker: Error response from daemon: Get “https://registry-1.docker.io/v2/”: tls: failed to verify certificate: x509: certificate signed by unknown authority.
See ‘docker run --help’.
i dont have man in the middle attack nor problems with the CA of my host
