There is no out-of-box support for "backing up all installed apps packages" Deepin AppStore currently.

However you can get deb files of all installed packages with this command:

dpkg -l | grep "^ii"| awk ' {print $2} ' | xargs sudo apt-get -y install --reinstall --download-only

Copy the Code

Note that this command will download a lot of files (including packages shipped with os default installation). I have no idea of how to just download package debs that are installed after os installation.

Deb files are saved at /var/cache/apt/archives, you can then copy these files to the offline host, save at the same place. You can then run dpkg -i *.deb to install all these packages, if you don't need to install all but some of, read on.

Make sure the two hosts have the same /etc/apt/sources.list, then copy /var/lib/apt/lists/* to the offline host's same place, it's equivalent to running apt-get update on the offline host, then you can use Deepin AppStore to install apps (of course, just those has been installed on the online host are available).

Sure, you can double click or run "dpkg -i xx.deb" to install the deb file.

Note that, since most deb files have dependencies, you will have to figure out the dependency, and install all the packages. For example, firstly, run "dpkg -i" against a deb file, it will prompt you that there are unsatisfied dependencies, see the sample output:

$ sudo dpkg -i apache2-mpm-worker_2.4.7-1ubuntu4.1_amd64.deb
Selecting previously unselected package apache2-mpm-worker.
(Reading database ... 251531 files and directories currently installed.)
Preparing to unpack apache2-mpm-worker_2.4.7-1ubuntu4.1_amd64.deb ...
Unpacking apache2-mpm-worker (2.4.7-1ubuntu4.1) ...
dpkg: dependency problems prevent configuration of apache2-mpm-worker:
apache2-mpm-worker depends on apache2 (= 2.4.7-1ubuntu4.1); however:
Package apache2 is not installed.
dpkg: error processing package apache2-mpm-worker (--install):
dependency problems - leaving unconfigured
Errors were encountered while processing:
apache2-mpm-worker

Copy the Code

It shows that you will have to find deb file for apache2, in my case, it is apache2_2.4.7-1ubuntu4.1_amd64.deb, then run dpkg -i again:

$ sudo dpkg -i apache2-mpm-worker_2.4.7-1ubuntu4.1_amd64.deb apache2_2.4.7-1ubuntu4.1_amd64.deb

Copy the Code

You may have to repeat this process a couple of times.

I copy all deb in /var/cache/apt/archives , then run sudo apt-get install *** , it will run directly and the depend will be installed automatic.

You should use sudo instead of su. You don't have root password (and the root user does not have a password set by default). For example:

sudo dpkg -i xxx.deb

Copy the Code

论坛改版之后，老帖子里的一些符号显示不正常了。
官方的解释是普通用户没有使用代码的权限……
