[SOLVED] apt-get updates waste time requiring re-scanning my Debian dvds

mark_alfred · 03-06-2011, 06:21 PM

Hello. I have the eight Debian dvds listed in my sources.list, along with security, nonfree, and multimedia repositories. Whenever I update now, I get the following:

Code:

Media change: please insert the disc labeled                                   
 'Debian GNU/Linux 6.0.0 _Squeeze_ - Official i386 DVD Binary-8 20110205-17:27'
in the drive '/cdrom/' and press enter

It does this for all eight dvds, re-scanning them for the update. These dvds have already been scanned (from the apt-cdrom add command). New updates are NOT going to suddenly appear on these already scanned dvds, so this is a completely unnecessary endeavour. Is there a way to stop this? It didn't happen with Lenny, and I'd like to stop it with Squeeze.

comment them out of your sources.list

@mark alfred I'm surprised that you forgot.
It must be a new installation.

Btw I have the Dell Optiplex GX1 with 500Mhz cpu.

I actually did not forget. I use dial-up, so I prefer relying upon dvds rather than the internet for my the bulk of my sources.list. Previously an update would not require having to pull out and rescan all the dvds; this is something new (I just recently upgraded).

Hello. I posted this issue to an existing bug with the Debian developers of apt-get. An answer was provided. This answer has worked for the other user who posted the same bug, but I have not been able to use this answer to solve the issue on my computer. The developer stated,

The "attached patch" was a file named "apt-cdrom-fix.diff". I downloaded this file, and tried to use it:

Code:

debian:/home/mark/stuff/upgrade_notes# patch < apt-cdrom-fix.diff
patching file acquire-item.cc
Hunk #1 FAILED at 861.
1 out of 1 hunk FAILED -- saving rejects to file acquire-item.cc.rej
debian:/home/mark/stuff/upgrade_notes#

Does anyone know what I'm doing wrong? I still have "apt-get update" demand all the listed DVDs to be rescanned.

Did you try to manually patch the file? It was only a couple of lines long.

This patch is meant to be applied to the source code of apt-cdrom. After that you have to compile that source code and install the new compiled program (preferably after you packaged it). It is not meant to fix the already installed program.

I really am not familiar with the patching of files, either manual or automatic (or whatever). In fact, the response to the bug report was the first I had ever heard of patching a file. So, I did an internet search, and came up with "patch < file.diff" as something to try. If you could let me know how else I can approach this (manually, automatically, or anyway) then I would much appreciate it.

Ah. Thanks. That's helpful. I'll try to get the source, and screw around with that for a while. Hopefully I'll be able to solve this issue.

Success! I enable deb-src repository, got the source, applied the patch, created the deb file, installed it, and now I can update without having to insert all eight DVDs for rescanning. I'm glad that irritation is gone.

hi mark_alfred!.

I have the same problem!. Could you explain solution step by step?, please

Thanks for all.

mark_alfred · 03-20-2011, 09:58 AM

I pretty well described everything above. See the manual for tips on working with sources.

I had similar problem yesterday,
It was due to backports being listed different
deb http://backports.debian.org/debian-backports squeeze-backports main
deb http://www.backports.org/debian lenny-backports main contrib non-free
