我已设置了两个客户端，一个是 18.04，一个是 20.04。这些客户端现在将从 REPO 服务器下载更新
18.04 源列表 /etc/apt/sources.list 包含以下条目：
root@vm-ubuntu18:~# cat /etc/apt/sources.list | grep allow
deb [allow-insecure=yes] http://10.0.0.4/ubuntu/mirror/azure.archive.ubuntu.com/ubuntu/ bionic main restricted universe multiverse
deb [allow-insecure=yes] http://10.0.0.4/ubuntu/mirror/azure.archive.ubuntu.com/ubuntu/ bionic-updates main restricted universe multiverse

deb [allow-insecure=yes] http://10.0.0.4/ubuntu/mirror/security.ubuntu.com/ubuntu bionic-security main restricted universe multiverse

从 18.04 服务器运行 apt 更新时，它运行正常并连接到我的 REPO。

20.04 源列表文件中应该包含什么才能连接到 IP 为 10.0.0.4 的本地 REPO 并下载软件包而不会出现错误？
谢谢

我最近将所有系统从 18.04 升级到 20.04（包括本地镜像）时遇到了这个问题。
问题在于“命令未找到”文件，这些文件显然在 18.04 中不存在，或者至少工作方式不同。我必须将这些行添加到镜像下载后运行的脚本中以解压缩文件。
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-security/main/cnf/Commands-amd64.xz
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-security/multiverse/cnf/Commands-amd64.xz
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-security/restricted/cnf/Commands-amd64.xz
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-security/universe/cnf/Commands-amd64.xz
#
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-updates/main/cnf/Commands-amd64.xz
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-updates/multiverse/cnf/Commands-amd64.xz
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-updates/restricted/cnf/Commands-amd64.xz
unxz -fk /[mirror location]/us.archive.ubuntu.com/ubuntu/dists/focal-updates/universe/cnf/Commands-amd64.xz
我可能手动解压了基本发行版的文件，我记不清了。可能我解压了，但没有在脚本中放入相关命令，因为这些文件不会改变。所以这是一次性的事情。
我使用的apt-mirror版本很遗憾没有维护，需要进行一些其他调整才能使其与 20.04 兼容 - 但似乎您没有使用它。所以我所做的可能对您不起作用，但最重要的是，您需要提取这些 cnf 文件，以便检查sudo apt update对客户端正常运行。
