    Hi mate,
    Trying to update kernel since it affected by Copy Fail & Dirty Frag Vulnerability. But it show an error.

    Code:
    dnf --refresh upgrade
Errors during downloading metadata for repository 'mariadb':
  - Status code: 404 for http://mirror.aarnet.edu.au/pub/MariaDB/yum/10.5/centos8-amd64/repodata/repomd.xml (IP: 202.158.214.106)
Error: Failed to download metadata for repo 'mariadb': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

    Does this have anything to do with mariadb yum repo?

    Thanks

    Nginx 1.31.x
    MariaDB 10.x/11.4+/12.3+
    Yes MariaDB yum related try the following command
    Code (Text):
    cmupdate

    run and exit centmin.sh menu once
    Code (Text):
    centmin

    then try
    Code (Text):
    dnf --refresh upgrade

    if that doesn't work you probably need to update to MariaDB 10.6 via centmin.sh menu option 11 submenu option 10 first as MariaDB 10.5 is end of life

    or skip MariaDB upgrade for now to get YUM updates
    Code (Text):
    dnf --refresh upgrade -x mariadb
