have been fine so far with installing new programms with apt-get.

recently i can´t do anything with it. always get after apt-get check:

Reading Package Lists... Done

You might want to run Apt-get -f install' to correct these.
Sorry, but the following packages have unmet dependencies:
libqt3-mt-dev: Depends: libxcursor-dev but it is not installed
E: Unmet dependencies. Try using -f.

when trying apt-get -f install i get an error from dpkg

i dont get the problem. tried to apt-get clean. after that tried to get the
missing dependency libxcurser... but had the same error when using dpkg to
unpack it.

dont have any idea anymore.
thanks for any hints.

See http://bugs.debian.org/222067

thanks a lot for the link.

now i know that i have an unofficial version of xlibs-dev.

but since i am a complete newbie i don´t really know how to do that. do i have to remove the directory /usr/share/doc/ where it lies (as far as i can trust ´locate´ or do i do this with apt-get?

do i have to apt-get the new package then form http://packages.debian.org/xlibs-dev?

sorry for askin such a probably obvios question. but i just want to be shure what i am removing in order not to destroy the working parts of my system.

many thanks

Don't remove your /usr/share/doc. Deleting it deletes all the documentation of all the packages in your system.

Also, to locate which package contains a file foo, you can run 'dpkg --search foo' (or faster version, if you have installed dlocate package: 'dlocate foo'), and to locate which files are contained in package foo, you can run 'dpkg --listfiles foo' (or again: 'dlocate foo')

What debian version are you using? (That is, how did you install your debian and what is the contents of /etc/apt/sources.list and /etc/apt/apt.conf) The package libxcursor-dev exists only in the testing/unstable, so you are probably using one of them.

Afther reading your first post more carefully, I found out that '692 not upgraded.' which sounds quite strange too.


What to do next?

• Check that the contents of /etc/apt/sources.list are correct (or more precisely: that they define package lists for the distribution you want to use).
• Run 'apt-get update' and 'apt-get dist-upgrade' and see if the problem gets fixed.
• If not, is the problem same? If it is, then you could probably have to manually update the xlibs-dev. (how it got wrong in the first place? Installed from knoppix?)

And the problem is still here? Ok, the hard way. Here is how to update xlibs-dev manually. Two steps. a) Retrieve the correct debian package and b) install it.

Retrieving:
The version number of the file depends on the distribution you are using (and there are also local mirrors you should be using when you retrieve many packages).
For unstable: http://ftp.debian.org/debian/pool/ma....1-14_i386.deb
For testing: http://ftp.debian.org/debian/pool/ma...-12.1_i386.deb
For stable: http://ftp.debian.org/debian/pool/ma...oody1_i386.deb
So either say: 'wget yourURL', or use your favorite browser to get those files.
(these could be normally retrieved automaticly by apt and could be easily retrieved by using packgages.debian.org, but it is down for the moment)

Installing
Run as root: 'dpkg -i yourxlibspackage.deb' (for example in stabe run: 'dpkg -i xlibs-dev_4.1.0-16woody1_i386.deb') in the directory where you retrieved your package.

Now the problem should be fixed and other packages should be installable again.

Finally
Don't forget to came back here and reply on how did it go and ask for possible additional questions.

Bear in mind that packages.debian.org may still be having problems after the break-in.

thanx for the help and links.

think i finally got the right package and tried to install it but i hit a new problem: this are the last lines of -apt-get -f install:

and now it seems the problem is getting more and more frightening to me. read about bad ram and real hardware problems..
what is the matter with locale-gen?


regards

If you're scared about bad ram try: MemTest86. Run it for about half an hour, but it will be evident immediately if you have bad ram.

After getting yourself out of the first mine, looks like you hit to an other one:
http://bugs.debian.org/198099

Ok, this will take me a while.

my system is crashing down now once in a while which never happened before. whell not exactly crashing completely. kde is dead and with ctr-alt-f6 i still get a command line but i have strange patterns of colors in front of the shell so i cannot do anything but to lock in as root and reboot. that is still something. after rebooting i am able to work with it for a while untill the next crash...

but never mind- i´ll somehow manage it in the end i hope.

but first of all thanx for all the help so far and merry x-mas. at least i won´t be bored the next days.

After trying this and that i always ran into "Segmentation Fault"
Scince it was not the ram which i had tested i lost my patience and got a new computer on which i am running gentoo now and it works perfectly well.

so thanks for your help anyway. i am waiting now for the next problems to show up and i hope it won't be too soon.
