How to include external deb files as dependencies?

[ukreddy-erwin]

With below command, I can create an empty deb package with a post installation script and few apt packages as dependencies.

fpm -s empty -t deb -n test -d python3 -d python3-pip -d vim --after-install ./postinst

Above, we are able to set apt packages available in the apt repository as dependencies. But, how to reference apt deb packages which are available as .deb files as dependencies?

I am trying to use fpm for the package management.

     apt-get install -y ruby-dev build-essential
     gem install fpm

After installing fpm, With below command, I can create an empty deb package with a post installation script and few apt packages as dependencies.

fpm -s empty -t deb -n test -d python3 -d python3-pip -d vim --after-install ./postinst

Above, we are able to set apt packages available in the apt repository as dependencies. But, how to reference apt deb packages which are available as .deb files as dependencies?

I tried including those deb files in the source to package and run them in post/pre install script, but getting error as apt process is locked, which I guess the current deb package created will be using, so this way is not useful.

Please suggest.

To the best of my knowledge, apt-get cannot do this, or at least, I can't remember a time when I've seen it done.

As you found in your example, you get an error 'apt process locked' (or similar) if you attempt to invoke apt-get install from a post install script. This is a feature of apt-get trying to protect itself from conflicting installation activities.

Can you tell me more about your goals? Can you show me (or describe) the ./postinst file contents?

My goal is to include two other Deb files(which are in public S3 bucket now shared) as dependencies, so it should install them before installing the fpm package create by me.
