CentOS7.9同步Ubuntu18.04.5软件仓库配置
1、安装Debmirror同步软件yum install debmirror -y2、配置debmirror.conf
# cat /etc/debmirror.conf
# Default config for debmirror
# The config file is a perl script so take care to follow perl syntax.
# Any setting in /etc/debmirror.conf overrides these defaults and
# ~/.debmirror.conf overrides those again. Take only what you need.
#
# The syntax is the same as on the command line and variable names
# loosely match option names. If you don't recognize something here
# then just stick to the command line.
#
# Options specified on the command line override settings in the config
# files.
# Location of the local mirror (use with care)
# $mirrordir="/path/to/mirrordir"
# Output options
$verbose=0;
$progress=0;
$debug=0;

3、调整同步脚本
#### Start script to automate building of Ubuntu mirror #####
## THE NEXT LINE IS NEEDED THE REST OF THE LINES STARTING WITH A # CAN BE DELETED
