I get this when I try to enable the driver for my graphics card:

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

Anyone able to help?

I'm a newcomer to Linux btw.

what linux os?
what version of distro?
what graphics card?

Hardy Heron 8.04, Nvidia 256 Meg card in a Sony Vaio.

For more detail- tell me how to find out!

i think that you may need to find out the exact model of graphics card,

My Computer - right cick go to properties
then hardware tab(?) and device list

that is all i can give, i was lucky my computer and card worked straight off the bat,

and its a weird 4 screen graphics card

Forgive my ignorance- I would need to be using Windows for the MyComputer thing?

(No warranty supplied, not least because i've never used debian or ubuntu on anything that had more than a text console display)

The error sounds like it's bitching that it's not happy with something about the current install state
of packages - at a complete random guess (which is all this is) maybe something you tried to install before didn't end up being marked (as far as the package management stuff is concerned)
as properly installed and configured.

That's what the dpkg manual page ("man dpkg" or http://www.wlug.org.nz/dpkg(8) ) suggests:
"dpkg --configure package ... | -a | --pending

Reconfigure an unpacked package. If -a or --pending is given instead of package, all unpacked but unconfigured packages are configured."

So, and again this could well be wrong, I'd reckon try doing "dpkg --configure -a", if it's ubuntu with the graphical desktop you'll probably need to open a "terminal" window and do "sudo dpkg --configure -a" in it, which might just work or might ask stuff :

I hope this helps but I hope more someone who knows Linux/Ubuntu more than I do (my job's unix stuff but sadly only ancient no-graphics stuff on FreeBSD) Google might help with any error messages though, I think Ubuntu's got better forum answers than most linux distributions)

Similar thing on ubuntuforums.org:

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the p - Ubuntu Forums

But who knows?

lspci

or

more /var/log/Xorg.0.log

you could try grepping nvidia to make the search easier

more /var/log/Xorg.0.log | grep nvidia

my regexp knowledge is poor, that will probably only search for its instance in that case, VB or someone else could tell you how to make that non case sensitive.

The location of the log file may be different in ubuntu, this is redhat/fedora location.
In my log here the first reference is to the card is unknown type, but further on it recognises the chipset in use and finally resolves the model name/number. Of course as you are getting an error it may not get that far.

Try removing the nvidia package, getting the package manager to do a clean up, then re installing the nvidia package.
Again concepts from my redhat/fedora use, I assume the ubuntu package system is similar.

Nerds.

(Gentoo ftw! emerge world!)

I'm a n00b to Linux too, I don't even know what +imMe's commands do!

But I used this script:

http://albertomilone.com/nvidia_scripts1.html

to install the correct nvidia driver for ubuntu. Worked very well. Not sure if that is helpful to you, I hope so.

Ubuntu doesn't support my new P45 board so trying out fedora now.

http://www.linuxquestions.org/questions/ubuntu-63/dpkg-configure-a-error-361965/ has the same problem explored, one solution seems to be to delete a folder and another to run the command that is suggested by the error..

Rtfm!

Just kidding.

horatio: God, I didn't know people are still doing Gentoo? I thought everybody had died from pulling their hair out while waiting to compile everything!
