Red Hat Enterprise Linux 8.5 -> 检查更新 -> 无法下载 repodata/repomd.xml：已尝试所有镜像

Question

I want to update GCP Instance where Red Hat Enterprise Linux 8.5 is installed. When I try 'sudo dnf check-update' I get an error:

 Error: Failed to download metadata for repo 'rhui-codeready-builder-for-rhel-8-x86_64-rhui-debug-rpms': Cannot

download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

If I try ' curl -I https://cds.rhel.updates.googlecloud.com ' I get response:

 HTTP/1.1 200 Connection established curl: (60) SSL certificate problem: self signed certificate in certificate chain

Do you have any suggestions how to make it work?

Answer 1

Error: Failed to download metadata for repo 'rhui-codeready-builder-for-rhel-8-x86_64-rhui-debug-rpms': Cannot

The above error might have caused because of many reasons:

Network connectivity to the rhel repo License issues Temporary glitches

We can rule out.network connectivity issues since you were able to crul the repo url. If you are using your own license check whether your license is active and if you are using google repos try to disable the repo and enable it again and then run the update command

dnf --disablerepo="*" --enablerepo="google-compute-engine" install google-rhui-client-rhel8

dnf update

If you are using any proxy in your gcp environment try to check that necessary configs are available.
