在使用AlmaLinux 8 系統遇到以下報錯的解決方法：
Errors during downloading metadata for repository 'baseos': - Curl error (6): Couldn't resolve host name for https://mirrors.almalinux.org/mirrorlist/8/baseos [Could not resolve host: mirrors.almalinux.org] Error: Failed to download metadata for repo 'baseos': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for https://mirrors.almalinux.org/mirrorlist/8/baseos [Could not resolve host: mirrors.almalinux.org]
這樣的情況因為系統的DNS出現問題所致，或許因為某些情況原有的DNS被清空了，你只要重新設置系統的DNS，一切回復正常。
