From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to download ALL dependencies for an external .deb package (rescuezilla)? (lemm.ee)

Hi everyone! I'm trying to prepare a live iso with a USB stick including the additional rescuezilla package (or, alternatively, additional packages for a live rescuezilla .iso). Sadly rescuezilla does not support encryption, and so I'd like to be able to create/encrypt an image on one single live iso, not having to do a double iso boot just for this. I'm trying to do this in a manner that I won't need internet once I need to use this USB stick. And hence...I found the most quoted command as:

apt-get download $(apt-rdepends |grep -v "^ ")

But this seems to work ONLY if your package is also part of the repo. If it's an external .deb such as rescuezilla_2.4.2-1_all.deb is, then the command just fails with:

Reading state information... Done
W: Unable to locate package ./rescuezilla_2.4.2-1_all.deb
E: Handler silently failed

So...what can I do to download the many dependencies of rescuezilla onto a USB stick? Thanks!

I’m not at a computer to verify, but dpkg -I package.deb will list dependencies of a deb file, so apt-get download $(dpkg -I rescuezilla_2.4.2-1_all.deb) might work.

apt-get download $(dpkg -I rescuezilla_2.4.2-1_all.deb)

Thanks a lot! While it wasn't as simple as that, it did indeed point me onto the right direction. This command did the trick for me:

apt download $(dpkg -I rescuezilla_2.4.2-1_all.deb | grep -oP '(?<=Depends: ).*' | tr -d ',')

The grep goes there to list only what comes after "Depends:". The -oP enables the python command to remove the string matching itself, so it leaves the whole list after the match... otherwise it also tries to download a package named "Depends:". And the tr -d ',' is to remove the commas separating each package, otherwise it fails to find them.
