[Software] use debian dvd to handle packages

[zio_civettone]

I use VMware to run Debian client where I configured 3 cdrom device (SCSI type), I ask myself if Debian can mount 3 cdrom at the same time.
I created 3 mount points that is /media/dvd1, /media/dvd2, /media/dvd3 for three dvd rom which contain Debian installer.
I mounted these 3 physical dvd to mount points so I can access them.

My target is to configure synaptic to handle packages only from my DVDs.
I don't know how to link dvd to Synaptic because Synaptic gives an error when try to add "add cdrom" function.

What is the error ?

[p.H]

IIRC apt expects the CDROM to be mounted on /media/cdrom.

[zio_civettone]

can I have only one cdrom ?

[p.H]

Not sure, I have never used multiple installation CDROMs. Maybe you can point the /media/cdrom to the desired CDROM mount point when prompted by apt.
Or create "deb file:" entries for each CDROM in /etc/apt/sources.list (see man sources.list). IIRC CDROM repositories are not signed, so you may need to mark them as safe/trusted (see man apt-secure)

So Synaptic use sources.list file ? If I changed this file adding 3 mount points of 3 cdrom, Synaptic retrieve info rightly ?

[p.H]

I guess so. Why don't you just try it and report ?

[zio_civettone]

I tried to mount /dev/sr0 to /media/cdrom, when I click on add cdrom in Synaptic an entry is added into It no cdrom is no longer mounter into /media/cdrom. How Synaptic can retrieve packages from cdrom ??!??!?!

How Synaptic can retrieve packages from cdrom ?

Why?
Originally in a disc set the index is on disc1. Installed from that disc, the sources.list entry is set by the installer, debs on disc+1 are known and the user will be prompted for disc#. The logic used is not intended for multi-device, yet you could set it up for no good reason.

Genuine disc changers at one time in history cached contents and could prompt user, or automatically cycle disc. I have a few of those, Nak's and Pioneers.

Post install there is no reason to use physical opticals in a virtual machine, except just for fun.

Search here for scanpackages, from dpkg-dev, move all debs onto a virtual drive and operate from there. You could use an iso format for fun if you must.
