This article will explain in detail how to use the apt-clone of linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Using apt-clone can help you back up installed packages and restore them in a newly installed Ubuntu system. If you have multiple Ubuntu systems that need to install the same set of packages, apt-clone can help you improve efficiency and accomplish this task quickly.

How do I install apt-clone?

The apt-clone package can be found in Ubuntu/Debian 's official repository, so use the apt package manager or the apt-get package manager to install it. Use the apt package manager to install apt-clone.

How does $sudo apt install apt-clone use apt-clone to back up installed packages?

After successfully installing apt-clone. Just provide a location to save the backup file. We will save the installed package backup in the / backup directory. Apt-clone saves the list of installed packages to apt-clone-state-Ubuntu18.2daygeek.com.tar.gz.

$sudo apt-clone clone / backup

We can also check by running the ls command.

$ls-lh / backup/total 32K Murray rwmurf RW Murray Rafe-1 root root 29K Apr 20 19:06 apt-clone-state-Ubuntu18.2daygeek.com.tar.gz

Run the following command to view the details of the backup file.

$apt-clone info / backup/apt-clone-state-Ubuntu18.2daygeek.com.tar.gzHostname: Ubuntu18.2daygeek.comArch: amd64Distro: bionicMeta: libunity-scopes-json-def-desktop, ubuntu-desktopInstalled: 1792 pkgs (automatic) Date: Sat Apr 2019: 06:43 2019

Based on the above output, there are a total of 1792 packages in the backup file.

How do I restore a software package that uses apt-clone for backup?

You can use any remote copy program to copy files on the remote server.

$scp / backup/apt-clone-state-ubunt-18-04.tar.gz Destination-Server:/opt

After the replication is complete, use apt-clone to perform the restore. Use the following command to restore.

$sudo apt-clone restore / opt/apt-clone-state-Ubuntu18.2daygeek.com.tar.gz

Note that the restore will overwrite the existing / etc/apt/sources.list and install / remove the package. So be careful. If you want to restore all packages to folders instead of actually restoring them, you can use the following command.

Sudo apt-clone restore / opt/apt-clone-state-Ubuntu18.2daygeek.com.tar.gz-- this is the end of the destination / opt/oldubuntu article on "how to use the apt-clone of linux".
