在Docker上创建本地Ubuntu存储库

Question

1. mkdir -p /root/repo/amd_64
2. copied all debian packages in /root/repo/amd_64
3. create the script /usr/bin/update-mydebs.sh with the following content:
#! /bin/bash
cd /root/repo/amd_64
dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz
4. Run the script update-mydebs.sh (I verified the Packages.gz is 
correctly created under /root/repo/amd_64)
5. Added the line in /etc/apt/source.list
deb file:/root/repo amd_64/

我也有这个问题。我花了很多时间搜索：https://github.com/radeno/polyfill-service-docker/blob/master/dockerfile

附注：

# work around the following APT issue by using "Acquire::GzipIndexes=false" (overriding "/etc/apt/apt.conf.d/docker-gzip-indexes")
#   Could not open file /var/lib/apt/lists/partial/_tmp_tmp.ODWljpQfkE_._Packages - open (13: Permission denied)

在作为update命令的一部分添加之后，这与本地存储库的预期效果一致。
