Say I want to install ffmpeg on similiar but networkless computer then which files I will need & will the commands be "deb -i file.deb".

You could try

Code:

cannabis:/home/repo# apt-cache depends ffmpeg
ffmpeg
  Depends: libavcodec52
  Depends: libavdevice52
  Depends: libavfilter0
  Depends: libavformat52
  Depends: libavutil50
  Depends: libc6
  Depends: libpostproc51
  Depends: libsdl1.2debian
  Depends: libswscale0
  Suggests: nvidia-libvdpau1
cannabis:/home/repo#

The command to install a deb file is

Code:

dpkg -i foo.deb

Okay i tried to search *.deb files in / but no result.Where can i find the files that were downloaded because as you can see in my previous post the links end up nowhere.

repo · 10-12-2009, 08:21 AM

They are in

Quote:

/var/cache/apt/archives

You need to use

Code:

find / -name "*.deb"

sumeet inani · 10-12-2009, 08:47 AM

to repo
Sorry for asking such a stupid question previously.
i found the .deb files then if I install them in order they have been downloaded using 'dpkg -i packagename'.then the software will get installed on networkless machine.is it true or there are some settings which apt-get does?

repo · 10-12-2009, 08:50 AM

You can install them on the networkless machine.
cd to where the files are on the machine and type:

Code:

dpkg -i *.deb

sumeet inani · 10-12-2009, 09:22 AM

Is there a way I can get the file-names that will be installed during software installation before downloading begins.

repo · 10-12-2009, 09:27 AM

Code:

apt-get -s install packagename

see

Code:

man apt-get

SOLUTION FOR ALL
This is compilation of all useful suggestions from various members.
Run all commands below as ROOT
(1)if you want to know what packages will be installed before downloading anything
apt-get install -s software_name
You can even download them from somewhere else & install on your computer offline using step 3.For ubuntu search site is https://launchpad.net/ubuntu/
(2)If you want to save downloaded debian files so that in future you can install software without internet ( recommended to be done since fresh install so that you can track system changes from start )
(a)run 'apt-get install software_name'(without quotes as usual)
(b)copy debian files from /var/cache/apt/archives.Put those files in folder 'software_name' in your backup-partition.Now run 'rm /var/cache/apt/archives/*.deb'(without quotes).
(3)Now whenever you want to install that software again.Just copy debian files to /var/cache/apt/archives & run 'apt-get install software'(as usual).Thus you will not trouble server to download everytime.

Alternative
I even found out way to install software on machine which never ran 'apt-get update' hence 'apt-get install softwareName' would give 'No installation candidate' error.
Fear not.
Look at 7th post on http://www.linuxquestions.org/questi...mputer-778601/ (sumeet's third)

If this helps you Please thank me by pressing thumbs up button(in the same way I have thanked suggestions found useful).Thank You.

Sounds like you are doing things the hard way. Have a look at apt-offline.

Code:

apt-cache show apt-offline

for details.

Cheers,

Actually I was trying to save downloaded debian files to safe location in case user uninstalls the software or reinstalls OS(here /var/cache folder will be rebuilt).How does your command help?

Well that's quite random...
I had no intention of try to help with your tangent. If you want to post something off topic, start a new thread.

The original post wanted to know how to install the the same packages on a machine not connected to the network as they had on a network connected machine. That is what apt-offline is for.

Anything else you would like to know?

I tried this command.the output was

W: Unable to locate package apt-offline
E: No packages found

I also checked man page of apt-cache.It does not contain the word 'offline'.

Ok, seems that Ubuntu, in its wisdom, decided not to package it (ie. pull from Debian). Perhaps it's in the Universe repo (or whatever it is called).

"apt-offline" is the name the package. "apt-cache" is just a command for querying the apt database. You can get information about a package (assuming apt knows about it) with:

Code:

apt-cache show packagename

See the following links for info about apt-offline.

http://apt-offline.alioth.debian.org/
http://packages.debian.org/sid/apt-offline
