篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了迁移Linux mint 18.2 apt到Ubuntu Server 16.04 LTS相关的知识，希望对你有一定的参考价值。
1、问题描述
这里有两台主机，其中
192.168.1.4上安装的是Linux Mint 18.2 Sonya系统。主机名是qwfys，用户名是lwk。
192.168.1.25上安装的是Ubuntu Server 16.04.3 LT系统。主机名是ubuntu，用户名是lwk。
当在192.168.1.25上输入命令apt的时候这样的：
[email protected]:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

[email protected]:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial
[email protected]:~$ apt
apt 1.2.24 (amd64)
Usage: apt [options] command
apt is a commandline package manager and provides commands for
searching and managing as well as querying information about packages.
It provides the same functionality as the specialized APT tools,
like apt-get and apt-cache, but enables options more suitable for
interactive use by default.
Most used commands:
list - list packages based on package names
search - search in package descriptions
show - show package details
install - install packages
remove - remove packages
autoremove - Remove automatically all unused packages
update - update list of available packages
upgrade - upgrade the system by installing/upgrading packages
full-upgrade - upgrade the system by removing/installing/upgrading packages
edit-sources - edit the source information file
See apt(8) for more information about the available commands.
Configuration options and syntax is detailed in apt.conf(5).
Information about how to configure sources can be found in sources.list(5).
Package and version choices can be expressed via apt_preferences(5).
Security details are available in apt-secure(8).
This APT has Super Cow Powers.

[email protected] ~ $ 有没有一种办法让Ubuntu Server 16.04.3 LT系统也拥有Linux Mint 18.2 Sonya那样的apt功能呢？
2、解决方案
让我我们先查找一下apt命令的出处吧。
在主机192.168.1.4上我们输入如下命令
[email protected] ~ $ whereis apt
apt: /usr/bin/apt /usr/lib/apt /etc/apt /usr/local/bin/apt /usr/share/man/man8/apt.8.gz
[email protected] ~ $ 在主机192.168.1.4上我们输入如下命令
[email protected]:~$ whereis apt
apt: /usr/bin/apt /usr/lib/apt /etc/apt /usr/share/man/man8/apt.8.gz
[email protected]:~$ 通过对比，我们发现Linux Mint 18.2 Sonya系统中的目录/usr/local/bin/下面多了一个apt文件。那么我们假定将Linux Mint 18.2 Sonya系统中的文件/usr/local/bin/apt复制一份放到Ubuntu Server 16.04.3 LT系统中的目录/usr/local/bin/下，会不会有效果呢，我们不防试一下。
在主机192.168.1.25上我们输入如下命令
[email protected]:~$ ll
total 36
drwxr-xr-x 4 lwk lwk 4096 Nov 23 00:06 ./
drwxr-xr-x 3 root root 4096 Nov 10 11:20 ../
-rw------- 1 lwk lwk 3479 Nov 23 00:03 .bash_history
-rw-r--r-- 1 lwk lwk 220 Nov 10 11:20 .bash_logout
-rw-r--r-- 1 lwk lwk 3771 Nov 10 11:20 .bashrc

-rw-r--r-- 1 lwk lwk 0 Nov 10 11:38 .sudo_as_admin_successful
-rw------- 1 root root 3433 Nov 23 00:00 .viminfo
[email protected]:~$ 确认主机192.168.1.25用户lwk主目录下没有apt文件。
这时，在主机192.168.1.4上我们输入如下命令
[email protected] ~ $ scp /usr/local/bin/apt [email protected]:~/
apt 100% 6329 6.2KB/s 00:00
[email protected] ~ $ 切换到主机192.168.1.25上输入如下命令
[email protected]:~$ ll

drwxr-xr-x 4 lwk lwk 4096 Nov 23 00:48 ./
drwxr-xr-x 3 root root 4096 Nov 10 11:20 ../
-rwxr-xr-x 1 lwk lwk 6329 Nov 23 00:48 apt*

-rw-r--r-- 1 lwk lwk 0 Nov 10 11:38 .sudo_as_admin_successful
-rw------- 1 root root 3433 Nov 23 00:00 .viminfo
[email protected]:~$ 这时候我们发现apt文件的归属不对，这里改一下，然后将其扔到/usr/local/bin/，然后查看有没有生效。
[email protected]:~$ sudo chown root:root apt
[sudo] password for lwk:
[email protected]:~$ ll
