@1130458020 这样尝试

1.手动更换系统源-换成清华源试试
2.使用一键安装，选择不清理系统源，仅更换帝三王源

主要错误可能是中科大的ubuntu-ports源问题

@1130458020 在第一步输入wget运行失败： failed: Temporary failure in name resolution. wget: unable to resolve host address ‘fishros.com’ 中说：

E: Release file for https://mirrors.ustc.edu.cn/ubuntu-ports/dists/focal-updates/InRelease is not valid yet (invalid for another 290d 0h 52min 19s)
