Re: broken synaptic/kpackage database

I'm no expert but I've had this a couple of times and all I did was delete the package to be overwritten AFTER a bit of research on Forums etc.

Needless to say BACK-UP first.

Otherwise wait for a 'guru' response when they return after the weekend!

Re: broken synaptic/kpackage database

Thanks for the reply. I was hoping for a way to resolve the seeming conflict. There seem to be two different packages that use the software binary Singular. Ah, well - hopefully one of the package managers knows how to deal or there's a trick I can use. I never ran into this in 10 years of SuSE, but I do like Kubuntu.

Re: broken synaptic/kpackage database

Are you using 'non-official' repos? That might explain the conflict.

You can force the installation of the offending package. For that, you open a console and go to /var/cache/apt/archives (please verify this path, I am not at a Linux box at the moment and my memory is a disaster).

Find the filename for the package and install it with

Code:

dpkg -i --force-overwrite <packagename>

Please take care though. You _may_ damage the other package, so do this at your own risk.

Re: broken synaptic/kpackage database

If what Xinixs suggested does not resolve it, try this:

Code:

sudo dpkg --configure -a

If you see an error message, it will probably tell you a lot about the nature of the problem.

Re: broken synaptic/kpackage database

Thanks! Is there a way to get some good output on the two packages that are conflicting? Not all the software needed is in an official repository! (or is that something they're trying to fix?) I think my problem comes from having Cantor with Singular support installed along with eSingular from the singular repo.

But what does it mean, Mr. Natural?

**dibl** · Feb 14, 2011, 05:38 PM

Re: broken synaptic/kpackage database

Mr. Natural suspects your system is suffering from the introduction of downloaded packages that are not synchronized with the versions of other packages upon which they depend. The Debian APT package management system is really very, very good -- but, you can defeat it by downloading and installing packages.

If you let Google guide you to the "ubuntu packages", and then follow "Maverick" to the packages, you'll find this version of singular:

http://packages.ubuntu.com/maverick/singular

and this version of emacs: http://packages.ubuntu.com/maverick/emacs

and I don't think those are what you have. I would try to remove the packages you installed:

Code:

sudo dpkg -r emacs

for example, and then reinstall them one at a time from the Kubuntu repo. It could work ..... :P

**PattiMichelle** · Feb 15, 2011, 09:47 AM

Re: broken synaptic/kpackage database

Thank you very much for the reply. I will try your suggestion. Specifically you can interpret that output and see that I need to get a different version of both emacs and Singular? I couldn't completely follow all the outputs of that debugging command - I couldn't really tell what the problem was, but I did see that singular-core and singular-core-static were causing problems and appeared to need to be installed. It looks like emacs was getting installed ok (from a good repo) but I am probably overlooking an error...

Thank you,
Patti

**dibl** · Feb 15, 2011, 10:58 AM

Re: broken synaptic/kpackage database

Hmmmmm. OK, the closer I look at that tiny print, the more it looks like you DID pull in the Maverick repo versions. Sorry for the suspicion otherwise.

I don't know those packages, but if it were me, first I would note those two packages that singular-icons is looking for, singular-core and singular-core-static.

Next, let's rip out singular:

Code:

sudo apt-get remove --purge singular

I think emacs did install correctly, but let's double check:

Code:

sudo apt-get update && sudo apt-get install --reinstall emacs

Did it go through with no errors? If so, good.

Now let's try again with singular, but let's start with the problematic packages:

Code:

sudo apt-get install singular-core singular-core-static

I don't know how much of the rest of singular this will pull in. Watch for errors. If you don't get error output, then do

Code:

sudo apt-get install singular

and see if it goes through.

Hmmm... I hope I didn't screw this up. I guess there are some repo errors, also.

Re: broken synaptic/kpackage database

No, you didn't hurt anything at all. Normally we simply pre-pend "sudo" to the command itself, rather than becoming root with "sudo sh", but that is not wrong (as long you don't forget to exit your "su" status before running a user command or package).

So, as far as I can tell, emacs is installed. Can you run the package?

It looks like singular has a problem. And it looks like you have a couple of duplications in your sources list, which not a problem for the system -- just an error message to let you know. What is the repository at http://files.lstandish.com/ d2x-xl/ Packages? Is that a trusted site? I'm not familiar with it.

Let's try following apt's advice:

Code:

sudo apt-get -f install

and see what happens.

yes, so far as I can tell *everything* runs just fine (eSingular, Singular, Cantor+singular). The only problem seems to be the package subsystem - it always throws that error. I don't really care about the error, but the updater won't run with that error and there are updates...

It's a game repo. I really liked Descent-II some years back, and would really like to have it to play. There are a couple versions built for linux now - but I couldn't get it to work under OpenSuSE11.x and I'm hoping it will work under K/Ubuntu since it's a very popular distro.

Re: broken synaptic/kpackage database

I think you must have a third party repo enabled, which has the newer version of singular, or perhaps part of it. Can you post the output of

Code:

sudo apt-cache policy singular*

It looks like you're right - I remember I couldn't find eSingular (the Singular-emacs interface) in the regular Kubuntu repos.
