How can I install additional packages using a file preinstall.sh?

[AlexanderLevashov]

Hello everyone. There is a specific problem. I need to install packages via preinstall, but the problem is that nfpm cannot unpack the archive. The following errors occur:

Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'hello' instead of './hello_1.0.3_amd64.deb' The following NEW packages will be installed: hello 0 upgraded, 1 newly installed, 0 to remove and 642 not upgraded. After this operation, 1 212 kB of additional disk space will be used. Get:1 /home/alexander/hello_test/hello_1.0.3_amd64.deb hello amd64 1.0.3 [570 kB] (Reading database ... 210508 files and directories currently installed.) Preparing to unpack .../hello_1.0.3_amd64.deb ... tar (child): php-8.1.13.tar.gz: Cannot open: No such file or directory tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now dpkg: error processing archive /home/alexander/hello_test/hello_1.0.3_amd64.deb (--unpack): new hello package pre-installation script subprocess returned error exit status 2 Errors were encountered while processing: /home/alexander/hello_test/hello_1.0.3_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1)

I know that the missing packages can be registered in depends in nfpm.yaml, but I need it through the preinstall process
As an example in preinstall.sh I have only tar -xvzf 8.1.13.tar.gz (just an example). And at the same time, if you make this file executable, then everything works, but not through nfpm. I ask for help, thank you.

can you share a minimum reproducible of this?

[caarlos0]

I understood that you got that error, still, can you share the minimal configurations/files needed to reproduce the error?

@caarlos0, thanks for the answers, I have already solved the question.

[caarlos0]

can you share what it was? it might be helpful to other people too :)

@caarlos0, sorry for long answer.
It's my own fault. For me, nfpm and the build of the distribution is basically a new thing, I haven't done this before. Firstly, I incorrectly specified the path in the files with the sh extension - this is the main error.
But that's not all. After I pointed out the right ways, another error occurred, this is secondly. T
he error was as follows, during the installation of the hello deb package, when the process reached the installation of dependencies (I used docker) then the following error occurs:
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
I solved this problem by writing an additional terminal call in the bash script, through which the command would be run: in my case;
sudo gnome-terminal --tab --title="Install_test" --command="bash -c'sudo apt install /docker.io_20.10.12-0ubuntu2~20.04.1_amd64.deb;'"

@caarlos0, I have another problem. Everything I described above, of course, works, dependencies are installed, but it looks very ugly, especially when an additional console is called.

The problem is this, there is an online machine that has Internet access and there is an offline machine that does not.

How do I build a deb package so that it immediately has a distribution, for example, the same docker. Because there will be no internet on the other machine.
Eventually run the command sudo apt install ./hello.deb
And so that both hello and docker are installed in the end. How do I do this?
