Im trying to create a apt cdrom repository. As a PoC Im trying to create a repository only containing what is needed to install vim.

I start by download the package and its dependecies

ls packages gives me

zlib1g_1%3a1.2.11.dfsg-0ubuntu2_amd64.deb

I create a packages index

dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

Lastly from the parent directory I create a image of the repo

genisoimage -J -R -V "Ubuntu update-iso" -o update-iso.iso packages/

On the machine where I would like to use the repository I mount the iso and register it as a cdrom repo.

apt-cdrom add
Using CD-ROM mount point /media/test/Ubuntu update-iso/

Lastly trying to install vim on the machine

apt-get install vim

...
Do you want to continue? [Y/n] 
Get:1 cdrom://test artful/main amd64 vim-runtime all 2:8.0.0197-4ubuntu5 [5,317 kB]
Err:2 cdrom://test artful/main amd64 vim amd64 2:8.0.0197-4ubuntu5
 File not found

Seems the runtime dependecy is found, but the vim package itself is reported as File not found. I can see that the package is in the iso.

vim_2%3a8.0.0197-4ubuntu5_amd64

and the package is listed in Packages.gz

Any ideas? Im really out of them..
