`Package '' has no installation candidate` when use `.iso` as debian 10 repo

Read posts about how to use iso as repo in debian system,as 1,2,3.

First,I downloaded 3 dvd .iso from debian 10 official site.
Then,

mkdir /media/cdrom1 /media/cdrom2 /media/cdrom3
mount -t iso9660 -o loop /home/mypc/Downloads/debian-10.9.0-amd64-DVD-1.256.c923fd.iso /media/cdrom1
apt-cdrom --no-mount -d=/media/cdrom1 add
mount -t iso9660 -o loop /home/mypc/Downloads/debian-10.9.0-amd64-DVD-2.256.b6990d.iso /media/cdrom2
apt-cdrom --no-mount -d=/media/cdrom2 add
mount -t iso9660 -o loop /home/mypc/Downloads/debian-10.9.0-amd64-DVD-3.256.6746e3.iso /media/cdrom3
apt-cdrom --no-mount -d=/media/cdrom3 add

Further,vi /etc/apt/sources.list

deb [trusted=yes] file:///media/cdrom1 buster contrib main
deb [trusted=yes] file:///media/cdrom2 buster contrib main
deb [trusted=yes] file:///media/cdrom3 buster contrib main

And apt-get update,output as below:

What's the problem when use .iso as debian 10 repo?
Thanks in advance.

Solution

  • File not found - /media/cdrom1/dists/buster/contrib/binary-amd64/Packages (2: No such file or directory)

    You need to remove contrib component from your /etc/apt/sources.list:

    deb [trusted=yes] file:///media/cdrom1 buster main
deb [trusted=yes] file:///media/cdrom2 buster main
deb [trusted=yes] file:///media/cdrom3 buster main

    The Debian DVDs contains only the free Software.

    To install aide package, you need to add the debian-10.9.0-amd64-DVD-6 to your sources.list.

    The debian-10.9.0-amd64-DVD-6 is available here, it can be downloaded through jidgo. See Downloading Debian CD images with jigdo.

    To know the content of Debian DVDs you need to download and extract the *.list.gz file from here. Every file will give the list of packages are contained in each Debian ISO.
