nothing helps to fix broken package manager.

[U202E]

If I want to remove/install update a package apt gives this error

libdrm-dev : Requires: libdrm-nouveau1a (= 2.4.42+git1302070925.20c560~gd~p) but 2.4.39-0ubuntu1 is installed.

and If I use sudo apt-get -f install it 'works' untill it gives this error:

dpkg: fout bij afhandelen van /var/cache/apt/archives/libdrm-nouveau1a_2.4.42+git1302070925.20c560~gd~p_amd64.deb (--unpack):
 trying to overwrite '/usr/lib/x86_64-linux-gnu/libdrm_nouveau.so.2.0.0', which is also in package libdrm-nouveau2 2.4.39-0ubuntu1
Fouten gevonden tijdens behandelen van:
 /var/cache/apt/archives/libdrm-nouveau1a_2.4.42+git1302070925.20c560~gd~p_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

^^"fouten" is dutch for "errors", for some reason apt is not 100% translated to the nl-NL locale.

I tried everything I was able to find on the internet! -but nothing helped.
And yes I have added some PPAs, but this 'broken' package is build succesfully according to https://launchpad.net/~oibaf/+archiv...vers/+packages
^^the .deb file from /var/cache/apt/archives/ is included as an attachment, it looks like a normal archive with no errors...

what's the (best) working fix I haven't found?
^^most apt/dpkg commands don't work, especially the ones I need; removing any PPA won't help. (even with the --force option)
most probably I have to manually edit something to make apt work again...
^^something like reverse enginering the .deb file or so.

info about my laptop:
ubuntu 12.04 64-bit (I am considering an upgrade, to quantal, raring or just keep using precise)
to install the mesa 9.0.2 with gallium I added the mesa9 and the optimized-drivers PPAs, probably it was a mistake to add the new ppa before removing the other one, now I have only the optim-drv one left.
the ppa: oibaf / Updated and Optimized Graphics Drivers

Try to remove libdrm-nouveau2 first

Try to remove libdrm-nouveau2 first

I can't use dpkg...
do you think deleting this with nautilus will help?
/usr/share/x86_64-linux-gnu/libdrm_nouveau.so.2.0.0

^there is a libdrm_nouveau.so pointing at this file.

[dino99]

sudo rm /var/cache/apt/archives/*

then try again

note: have you some ppa or extra repo activated ?

[schragge]

I can't use dpkg...

Even with --force-* options? Something like

sudo dpkg --force-remove-reinstreq -r libdrm-nouveau2

Or at least,

echo libdrm-nouveau2 deinstall|sudo dpkg --set-selections
sudo apt-get upgrade

do you think deleting this with nautilus will help?
/usr/share/x86_64-linux-gnu/libdrm_nouveau.so.2.0.0

^there is a libdrm_nouveau.so pointing at this file.

I wouldn't try it before all other options are exhausted.

sudo rm /var/cache/apt/archives/*

^^thanks for your reply, but it just removes a cache file; It doesn't help.
(Rm gave me an error because it can't delete an folder)
the deb file looks good, I can just open it with archive manager and view it's content.

note: have you some ppa or extra repo activated ?

as I mentioned before: yes, I added the optimized-drv and mesa9 ppa, then removed ppa:mesa9.

[U202E]

Even with --force-* options? Something like

sudo dpkg --force-remove-reinstreq -r libdrm-nouveau2

Or at least,

echo libdrm-nouveau2 deinstall|sudo dpkg --set-selections
sudo apt-get upgrade

I wouldn't try it before all other options are exhausted.

thanks for the options, I have tried all your commands and nothing helped.
when saying not able to use dpkg I meaned even with force...

and removing the /usr/lib... well I tried it it: I didn't remove it but I just moved it to desktop, and because nothing happened I moved it back.

do you think upgrading to quantal will fix this? or will it make things worse?

What does sudo dpkg -C show?

What does sudo dpkg -C show?

It looks like at least someone can help me...

this is the result:

De volgende pakketten zijn uitgepakt maar nog niet geconfigureerd.  Ze
moeten geconfigureerd worden met dpkg --configure of de menu optie
Configureren in dselect om ze te laten werken:
 libosmesa6-dev       Mesa Off-screen rendering extension -- development files
 libgl1-mesa-dev      free implementation of the OpenGL API -- GLX development 
 mesa-common-dev      Developer documentation for Mesa
 libdrm-dev           Userspace interface to kernel DRM services -- development

in case you're not dutch, it says ' these packages are unpacked but not configured, they have to be configured with --configure'

[schragge]

First, try to configure them one by one

sudo dpkg --configure libosmesa6-dev
sudo dpkg --configure libgl1-mesa-dev
sudo dpkg --configure mesa-common-dev
sudo dpkg --configure libdrm-dev

Then look again at the output of 'sudo dpkg -C'
