I have copied downloaded deb package when installing software from software center or terminal. Is it possible to make a single package instead of multiple package. Exp: Thunder bird have 3 package when i download it. Now i want to make standalone package.
Not without re-packaging everything with
I recommend you tar or zip up all the debs, extract them to a single directory, then
It's difficult to define precisely what the dependencies are. If there are three packages for Thunderbird on one machine, there might be a different number of dependencies to install on a different machine, unless you're considering adding together all of several thousand possible packages.
The thing is, each package has lots of dependencies. Some are already installed, and some aren't. So the package manager determines which ones aren't already installed and installs them--and those are the only ones it bothers mentioning to you, even though there are actually many more. Naturally, the list will vary from machine to machine depending on the other software installed.
You can reduce the possible number of dependencies to be separately installed by bundling some things together (at the cost of wasted space on machines that already have some of the bundled software), but you can't eliminate it.
Another issue is that sometimes a single source package is split up into several binary packages. Again, this is for greater efficiency. Perhaps you might not want to install all of a program. Or there might be some parts that are platform-independent and don't need to be built separately for different types of machines.
