[Bug 405577] [NEW] ISO Restored Cache Packages are Ignored by apt-get install

[Lonnie]

Public bug reported:

I'm trying to use AptOnCD ***without a CD/DVD***. Important the key here
is "without a cd/dvd".

Most tutorials imply that you can simply restore the packages from the
ISO, and then when you use "apt-get install" to install those packages,
apt-get will use the packages placed in cache by aptoncd instead of
downloading them again. However, apt-get ignores the packages restored
to cache by aptoncd, rendering that feature useless as far I've been
able to achieve.

Restoring packages using AptOnCD, from an ISO, accomplishes nothing that
“apt-get install” will use.

Yes, if you create a CD or DVD using AptOnCD, you can then go to "System
> Administration > Software Sources > Third Party Software > Add CD-ROM"
and use that CD/DVD as a primary package source while installing via
"apt-get install", therefore eliminating the need to download those
packages again from their original repositories.

However, "Software Source > Third Party Software > ADD CD-RO” offers no
way for you to use an ISO image (created by AptOnCD) as a source to
accomplish the same thing. I've found no convenient way to effectively
use my AptOnCD ISO image without first creating a physical CD/DVD.

You'd think that the “restore” feature in AptOnCD, would prevent “apt-
get install” from re-downloading the packages from the Internet
Repositories, but this is NOT the case. Although the “restore” feature
does indeed copy the packages from the AptOnCD ISO to the
“/var/cache/apt/archives” folder, “apt-get install” ignores them; when
you us “apt-get install”, it re-downloads the package despite the fact
that “AptOnCD restore” has placed the exact same package at
“/var/cache/apt/archives”!

Due to this post [http://ubuntuforums.org/showthread.php?t=541029], I tried to install of the packages (retored by atponcd to “var/cache/apt/archives”) using the following two comands:
cd /var/cache/apt/archives
sudo dpkg -i *.deb

After installing the packages in this manner, Errors were encountered while processing: 
 eclipse-gcj 
 eclipse-pydev-gcj 
 icedtea-6-jre-cacao 
 libfinance-quote-perl 
 libk3b3 
 libk3b3-extracodecs 
 liblapack3gf 
 libmatroska0 
 libtorrent-rasterbar2 
 libxcb1-dev 
 mencoder 
 miro 
 mkvtoolnix 
 mplayer 
 nvu 
 python-chm 
 python-libtorrent 
 python-numpy 
 quanta 
 sun-java6-plugin 
 thoggen 
 tovid 
 tovidgui 
 transcode 
 vlc-nox 
 winff 
 xvidcap 
 libx11-dev 
 libxt-dev 
 mozilla-mplayer 
 vlc 

Later, when I tried to reload software sources, I received and error
dialog that informed me that I had 28 broken packages. Additionally, it
rendered my laptop unable to boot back into Ubuntu! So, dpkg undermines
and corrupts Ubuntu's proper installation methods,

I've tried mounting the ISO image created by APTOnCD to the file system,
but "System > Administration > Software Sources > Third Party Software >
Add CD-ROM" will only find a physical CD/DVD. If you don't have a
physical CD/DVD, in your drive, you'll get the following message:
“Please Insert a disk in the drive”. I tried to learn the proper
protocol to construct my own apt line that  would add the “aptoncd  ISO”
as a software source:
[http://www.zimbio.com/Linux/articles/kEIN6zMahru/Add+iso+software+repository+Ubuntu},
but this too failed for me. I got “file not found”.

I tried mounting the cd rom, and then adding it as a sofward source using the apt-cdrom command:
sudo mount -o loop /home/lonnie/aptoncd-20090727-DVD1.iso /media/cdrom 
sudo apt-cdrom -m -d=/media/cdrom0 add

But the apt-cdrom command couldn't find any packages;  Here's what is said:
Identifying.. [37951917c86fd94b96086e5e34697542-2] 
Scanning disc for index files.. 
Found 0 package indexes, 0 source indexes, 0 translation indexes and 0 signatures 
E: Unable to locate any package files, perhaps this is not a Debian Disc 

Instead of taking the next step, of trying to figure out how to fool
Linux into thinking that my AptOnCD ISO is physically inserted CD/DVD
(instead of a mounted ISO), I've decided to write up this  document to
report this dilemma.

I simple want to use my AptOnCD ISO as a software source, ***WITHOUT
PHYSICALLY CREATING A CD/DVD***!

Also, I don't want to mount anything either. CDs and DVD are as
antiquated as floppy disks as far as I'm concerned (in world with 64 gig
thumb drives).

Why must this application be so dependent on  physically creating or
mimicing a disk?
