nothing helps to fix broken package manager.

[U202E]

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'

yeah, I can't configure them because dpkg says there are unmet dependencies.
, that didn't work.

it's like the chicken-and-egg -effect: because of the error I can't fix the error.

Ok, please post the output of

dpkg -l libdrm-nouveau2
apt-cache rdepends libdrm-nouveau2

quite surpricing to me that it says xserver....quantal, I am using precise.

Wait a minute, why do the packages from quantal show up in reverse dependencies of libdrm-nouveau2:

here you have it:

Answering to myself: they are from precise-updates.

Ok, then try (you can hit <TAB> several times to complete the file name)

sudo apt-get -d upgrade libdrm-nouveau1a
dpkg --force-overwrite -i /var/cache/apt/archives/libdrm-nouveau1a_2.4.42+git1302070925.20c560~gd~p_amd64.deb
sudo apt-get -f upgrade

^^looks clear, no quantal. perhaps it's an error with a package: made for quantal but distributed as precise.

[dino99]

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

so ppa-purge might be your friend (if you use it about that other optimized-drv)

so ppa-purge might be your friend (if you use it about that other optimized-drv)

it isn't, I considered it but then I thought "why install unnecessary packages?" add-apt-repository ppa:user:blahblah-ppah works just as well.

As far as I know ppa-purge can't fix this error.

I've already found out, see here. BTW, have you tried dpkg --force-overwrite as I suggested there?

At least I have tried sudo dpkg --remove --force-remove-reinstreq.
ok lets copy that code into the teminal...
thank you!!!!!!

looks like the force-overwrite did help.
while typing this firefox says I have to restart my browser because there is an updated version->if firefox is updated apt works again!
the error box dissapeared.

all updates installed without any error, now it doesn't feel like windows anymore
