Migrating Linux Mint 18.2 apt to ubuntu Server 16.04 LTS

1, problem description

There are two hosts, of which

The Linux Mint 18.2 Sonya System is installed on the 192.168.1.4. The hostname is Qwfys, and the user name is LWK.

The Ubuntu Server 16.04.3 LT System is installed on the 192.168.1.25. The hostname is Ubuntu and the user name is LWK.

When you enter a command on 192.168.1.25, APT is like this:

Is there a way to get the Ubuntu Server 16.04.3 LT system to have an apt function like the Linux Mint 18.2 Sonya?

2. Solutions

Let me look at the source of the APT command first.

On the host 192.168.1.4 we enter the following command

On the host 192.168.1.4 we enter the following command

By contrast, we found that the directory/usr/local/bin/in the Linux Mint 18.2 Sonya System had an apt file under it. Then we assume that the Linux Mint 18.2 Sonya System files/usr/local/bin/apt copied a copy placed in the Ubuntu Server 16.04.3 lt system directory/usr/local/bin/, will not have the effect of it, We don't have to try.

On the host 192.168.1.25 we enter the following command

[email protected]:~$ lltotal 36drwxr-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 .bashrcdrwx------ 2 lwk  lwk  4096 Nov 10 11:30 .cache/-rw-r--r-- 1 lwk  lwk   655 Nov 10 11:20 .profiledrwx------ 2 lwk  lwk  4096 Nov 10 11:42 .ssh/-rw-r--r-- 1 lwk  lwk     

Verify that the host 192.168.1.25 user lwk the home directory without the apt file.

At this point, we enter the following command on the host 192.168.1.4

[email protected] ~ $ scp /usr/local/bin/apt [email protected]:~/apt                                                                                                                                                                                                         100% 6329     6.2KB/s   00:00    

Switch to host 192.168.1.25 and enter the following command

[email protected]:~$ lltotal 44drwxr-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------- 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 .bashrcdrwx------ 2 lwk  lwk  4096 Nov 10 11:30 .cache/-rw-r--r-- 1 lwk  lwk   655 Nov 10 11:20 .profiledrwx------ 2 lwk  lwk  4096 Nov 10 11:42 .ssh/-rw-r--r-- 1 lwk  lwk     

At this time we found that the apt file belongs to the wrong, change it here, and then throw it to/usr/local/bin/, and then see if it takes effect.

So far, we have found that the APT command in the Linux Mint 18.2 Sonya System has been successfully migrated to the Ubuntu Server 16.04.3 lt system.
