Hi, I tried $sudo dnf repoquery lapack --srpm --location, and it returns http://mirrors.163.com/fedora/linux/releases/26/Everything/source/tree/Pa..., which do not exists. The correct address should be http://mirrors.163.com/fedora/releases/26/Everything/source/tree/Packages.... I don't know whether this is the correct place for this issue. Please forward this email to the correct place if this is not the correct mailing list. Thanks, yecheng
