[SOLVED ]Error upgrading packages, conflict libc6 amd64 i386

[amasglobulaires]

Hello everyone !

Since few days, I can't upgrade my debian desktop because of a conflict between two different version of libc6 , when I run

Code: Select all

sudo apt-get upgrade

.
I get this error :

Code: Select all

Preconfiguring packages ...
dpkg: error processing package libc6:amd64 (--configure):
 package libc6:amd64 2.19-18+deb8u10 cannot be configured because libc6:i386 is at a different version (2.19-18+deb8u9)
Errors were encountered while processing:
 libc6:amd64

I don't really know how to handle this problem, I would like to replace this old libc6:i386 package by the 64 bit version of it.
If you have any advice on how to simply do it, I would be very grateful !!

Thanks in advance !

# apt-get autoremove && apt-get install -f
What does that show?

I would like to replace this old libc6:i386 package by the 64 bit version of it.

And what exactly makes you think that this is necessary or desirable? Please be specific.

[amasglobulaires]

I would like to use the 64 bit package since this computer is a 64 bit machine . And also because this conflict between this two package seems to cause problems and prevent any upgrades.

For information

Code: Select all

uname -m

:
gives

Code: Select all

x86_64

I would like to understand why there is a conflict between these two packages.

Code: Select all

dpkg --print-architecture 
amd64

Normally dpkg doesn't accept i386 packages right ? .
So why it doesn't want to replace the old libc6:i386 package by the 64 bit version ?

[dasein]

I would like to use the 64 bit package since this computer is a 64 bit machine

Let me rephrase the question: What makes you think that the architecture of your machine is the overriding consideration underlying your question?

(In case it isn't obvious, depending on any number of factors, you are potentially one small mistake away from a major problem. You would be smart to do a backup before you do anything else.)

[amasglobulaires]

Well my main problem here is that I can't make any kind of upgrades, so my debian environment is actually stuck and won't take advantage of any security or features updates for any applications, and this problem seems to come from a conflict between a libc6 32 bit package and a 64 bit one .

In order to retrieve a safe environment by finally making these upgrades, do I have the choice between overriding the libc6 32 bit package or keeping it ? Can I have both ?

[dasein]

Well my main problem here is that I can't make any kind of upgrades...

No. Your main problem is that you have no idea about the implications of what you're trying to do and cannot articulate a coherent rationale for your actions.

Back up now. Seriously.

[amasglobulaires]

You have no idea about the implications of what you're trying to do and cannot articulate a coherent rationale for your actions

Yeah, that's why I asked for some advice and some explications, and I actually didnt took any action except trying to upgrade the environnement ( the normal way )and gathering some informations and errors . Moreover my actual rationale mind made me post my problem and my questions on this forum to gather some experience by people who understand my problem, and of course before doing anything stupid on my own.

The backup is done since a long time but thank you for having warned me.

Hi again,
So you're running Debian 8. Have you made any changes to /etc/apt/sources.list?

[amasglobulaires]

My actual sources from apt are these :

Code: Select all

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

deb http://httpredir.debian.org/debian/ jessie-updates main contrib non-free
deb-src http://httpredir.debian.org/debian/ jessie-updates main contrib non-free

deb http://httpredir.debian.org/debian/ jessie main contrib non-free
deb-src http://httpredir.debian.org/debian/ jessie main contrib non-free

deb http://repo.linrunner.de/debian jessie main

I'm thinking that maybe you can just remove the offending package with the dpkg package manager

Code: Select all

# dpkg -r libc6:i386

followed by

Code: Select all

# dpkg --configure -a

Since your running everything on an amd64 system, getting rid of it shouldn't mess anything up and besides, you've already backed up your files.

[stevepusser]

Many machines have both i386 and amd64 versions of that and other libraries installed; mine for example. The versions have to match, and they do on mine.

I would bet that you haven't run "apt-get update" to refresh your package database for a while, since it seems to be trying to use an older version of a library--or maybe you removed multiarch support somehow?

[amasglobulaires]

Well thank you for your help everyone !

maybe you removed multiarch support somehow?

You were right stevepusser, it missed the i386 architecture, I probably have an application i forgot about that need the libc6:i386

Code: Select all

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install -f
sudo apt-get upgrade

And I can properly make the upgrade !

[kedaha]

I'd give it a go.

[amasglobulaires]

Yup it worked just fine !
