Hello, I am newbie and I want to build deb package for ubuntu 18.04.

I found this article help me, https://askubuntu.com/questions/8481...771109a588bced.

My question is, Is it safe to build deb package using sudo privilege? Because I have to use sudo checkinstall instead of checkinstall to create the package.

TIA

Not sure exactly what you wish to do but this is a better page for a staring point on .deb packages I'd think. https://wiki.debian.org/HowToPackageForDebian

In that page they suggest a jail.

Pardon me the confusion. I am trying to create Debian package from source, eg nginx with mod-security. In the article I attached explain that to create debian package we can use checkinstall command line. I have tested it and it works well, but it needs sudo permission to build the package. I create the package in a vps server, then I copy the package to another vps server as a production server for blogging using WordPress. I want my production server have the software that I need and free from development software.

My question is, is it safe to create debian package in this way?

TIA

I would say, since you need to be root or sudo to install packages, same applies for checkinstall.
Here's a more appropriate link.

Hmm, I have been thinking, why should I create deb package if I can install it without creating the package.

If you install to your home directory you don't need sudo. The Homebrew package management system avoids sudo and uses this sort of technique to build packages. The reason you typically want to use some package manager to install rather than just installing without one is to make it easier to remove or update the package/library/program. It can also track dependencies for you if you're installing more than one library or application, so that modifying/updating/removing one library/application one doesn't mess up any others.

If you don't want to build a deb package directly but still want to use Debian package management, an easier method might be to build the package and during the make install have the package installed in a subdirectory under your home directory. Most makefiles have an install option for a destination directory (DESTDIR). Once the files are in a known location, you can gzip and tar the files to create a tarball. Then, you can use the alien program to create a .deb file from the tarball. You will still have to deal with the file permissions issue if you install outside your home directory though. Haven't found a better way to create a deb file (especially if my files are already in a tarball format), but would be interested to hear if someone knows an easier method.

I have tried to uninstall .deb package using this command line, but not working : sudo dpkg -r package.deb

Do you know why?

Hi again, Can I copy file from the jail directory to the outside directory, eg my "real home" directory?

Thanks

No, if you won't post details. We cannot see your host.

yes, you can copy, from outside you can see the jailed directory too (at least I think).

if in some way I can copy the file from inside chroot, Is it safe to use the file like install it on my vps?

Thanks
