Debian 11.1.0 DVD 2,3,4,5 ?

[Christoph Prokop]

Hi there,

i just downloaded DVD1 for 11.1.0 but it seems DVD 2,3,... are missing here:
https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/
Is it on purpose only DVD1?

This Site lists 1-5 (but i am not sure who provides theses isos):
Is this even an official mirror?

Greetings and thanks for all your efforts!

From Debian 11.0 onwards, we're ornly providing one DVD as standard.

It is a law of diminishing returns: we found fewer and fewer people
were downloading all three and yet people were continuing to get confused
by which DVD was bootablew and which was necessary

If you want to get DVD2 and DVD3 particularly, then you can use
jigdo-lite and .jigdo files. Most people don't in fact need them
because DVD1 will install sufficient / they're carrying out an
install while connected to the Internet anyway.

If you need more than one DVD's worth, another possibility is to use
the 16G file to put onto a USB stick / the Blu-Ray disk images which are
also bootable from USB stick.

It's possible that the admin of the mirror you cite just made the DVD
files up for convenience of their users.

cdimage.debian.org is the canonical source for CD / DVD and other Debian
media so check there first for changes, as you have done in this instance.

With every good wish, as ever,

Yep. Stated by Andrew M.A. Cater in

[...] the number of DVDs was [...] reduced for Debian 11. Whereas
for Buster we made the first three .iso images, for Bullseye there is
the others can be built using jigdo.

That would be
https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dvd/
.jigdo and .template files are to be used as described in
https://www.debian.org/CD/jigdo-cd/#how
I wrote a wiki article how to get to a Live Debian, install jigdo-lite
on it for the time it is running, and use it to download one or more
https://wiki.debian.org/JigdoOnLive
Maybe you find inspiration in there if riddles arise ...

Hard to say. Maybe they are just nice and did the jigdo work for you.
If you can afford the bandwidth to download the ISOs and to discard them
if they are bad, then check the downloaded ISOs by the checksums in
https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dvd/SHA256SUMS
and/or
<https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dvd/SHA256SUMSand/or>
https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dvd/SHA512SUMS
I.e. _not_ by the checksums on debian-cd.inspire.net.nz .

My advice, verify the checksums _without fail_, especially jigdo.
No matter how good you believe your internet service to be, nor how much
excess capacity your platform has.

A cautiously mistrusting downloader will want to verify the checksum
files by their .sig files and a run of gpg --verify.
Have a nice day :)

You're welcome.
I've seen checksum failures due to overloaded, overstressed OSs.
I've seen checksum failures due to faulty RAM.
When you're check summing billions of bytes....
....you forget how big a billion is :-)
