Error: Failed to download metadata for repo 'update': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
看源是：
[update]
name=update
baseurl=https://repo.openeuler.org/openEuler-22.03-LTS-SP4/update/$basearch/
metalink=https://mirrors.openeuler.org/metalink?repo=$releasever/update&arch=$basearch
metadata_expire=1h
enabled=1
gpgcheck=1
gpgkey=http://repo.openeuler.org/openEuler-22.03-LTS-SP4/OS/$basearch/RPM-GPG-KEY-openEuler
另外丢包也很夸张，咱能不能加个大陆总源呀 刚刚才发现域名原来没备案。。
