jigdo-lite uses ubuntu mirrors when downloading debian iso

[Przemek K.]

Binary package hint: jigdo

jigdo-lite uses ubuntu mirrors when downloading debian iso. This is wrong, jigdo should use debian mirrors.

-----------------------------------------------------------------
If you already have a previous version of the CD you are
downloading, jigdo can re-use files on the old CD that are also
present in the new image, and you do not need to download them
again. Mount the old CD ROM and enter the path it is mounted under
(e.g. `/mnt/cdrom').
Alternatively, just press enter if you want to start downloading
the remaining files.
Files to scan:

-----------------------------------------------------------------
The jigdo file refers to files stored on Ubuntu mirrors. Please
choose an Ubuntu mirror as follows: Either enter a complete URL
pointing to a mirror (in the form
`http://archive.ubuntu.com/archive/'), or enter any regular expression
for searching through the list of mirrors: Try a two-letter
country code such as `de', or a country name like `United
States', or a server name like `sunsite'.

Jigdo does not download mirror list from any server. Rather the mirror list is part of the package and can be found at /usr/share/jigdo/debian-mirrors.jigdo. It is intentional change to have Ubuntu mirrors in this file.

Marking as invalid. Please free to reopen.

This is essentially the reverse of #64743

The major bug here is that Jigdo is unaware of what it's looking for: it was created with the assumption of downloading Debian CDs from Debian mirrors, and isn't aware of a local cache of a mirror set or a remote copy of that mirror set.

Essentially, Jigdo knows there's mirror information in /usr/share/jigdo/debian-mirrors.jigdo as an absolute fact. On Ubuntu, we predict that the Ubuntu alternatives CDs will be downloaded with Jigdo if anything, and thus that file has Ubuntu mirrors. Jigdo doesn't know or care of any of this. If we leave Debian mirrors there, it breaks on Ubuntu CDs; Ubuntu mirrors, breaks on Debian CDs; try to use Jigdo for anything else and it fails.

The fix is to have Jigdo look for a mirror file referenced by the .jigdo, which is currently not a feature. Then of course you must get Debian to use it, or guess if the file is 'debian-*.jigdo' then use the Debian mirror list.

Status changed to 'Confirmed' because the bug affects multiple users.

Wow, I just got hit by this bug that’s over 15 years old! Although to be fair I’m running on Ubuntu Precise 12.04 LTE for which the latest jigdo is 0.7.3-3ubuntu1. In any case, I supplied this URL to jigdo:

http://mirror.as35701.net/debian-cd/current/amd64/jigdo-bd/debian-12.4.0-amd64-BD-1.jigdo

Jigdo was not smart enough to work out that the URL of the `.jigdo` file contains the mirror. It’s understandable that it would need to prompt the user for a mirror since .jigdo files can also be locally referenced instead of the URL, but the prompt should at least try to more smartly derive a default for the mirror prompt.

I was asked for the mirror with a default of some Ubuntu host. The default should have been mirror.as35701.net. It is also unclear from the prompt what it wants. Does it want just a hostname or a host and path? What format? I guessed and supplied this as the mirror:

http://mirror.as35701.net/debian-cd/current/amd64/jigdo-bd/

Jigdo was apparently smart enough to parse the hostname out of that, but it should also more clearly state what it’s asking the user for.

Jigdo was able to fetch the .template, but then it dropped the ball. That’s another bug which is reported here:
