Help with unresolvable dependencies

[TheEighthDwarf]

I've run into one of those unresolvable dependency problems I'd only heard about in back alleys and taverns of ill repute, and I'd be grateful for any help.

I use LMDE x64. I'm trying to install an R library called Rattle, which is for data mining, which requires a few things, such as libgtk2.0-dev. So I try to install it and this happens:

Code: Select all

$ sudo apt-get install libgtk2.0-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgtk2.0-dev : Depends: libgdk-pixbuf2.0-dev (>= 2.21.0) but it is not going to be installed
                 Depends: libpango1.0-dev (>= 1.20) but it is not going to be installed
                 Depends: libcairo2-dev (>= 1.6.4-6.1) but it is not going to be installed
E: Broken packages

I'm getting more things like this, like when I tried to install the HP LaserJet thingamabob ("hplip" or whatever). Here's my sources.list contents:

Code: Select all

deb http://debian.linuxmint.com/latest/multimedia testing main non-free

Suggestions?

Thanks in advance!

As i understand it, the 3 files mentioned at the bottom are too old for the program you want to install.

libgdk-pixbuf2.0-dev => you need version 2.21.0
libpango1.0-dev => you need version 1.20
libcairo2-dev you need version 1.6.4-6.1

Libcairo2 can be found here: http://packages.debian.org/search?keywords=libcairo2
libgdk-pixbuf can be found here: http://packages.debian.org/search?suite ... rds=libgdk
libpango can be found here: http://packages.debian.org/search?suite ... s=libpango

Make sure that you, beside the "standard" file, also installs the -dev fiule since this is the file specifically asked for.

Thanks for your answer.

So you recommend installing the older versions, replacing the newer ones I (think I) have?

If so, how do I do that? In Synaptic I don't see the older versions, and I'm not sure what to do with the versions on the page you linked.

Yes, replacing the old version with a newer version will solve your problem.

By updating the older version with a newer version, the older version will be overwritten by the new one.

http://packages.linuxmint.com/list.php?release=Debian here you can find the libcairo package.

There's also a bug report if this:

you have 2 options:
- check the pin priority and level all to 700, do a DU and then the libcairo2-dev v. that you want should be installed;
- in synaptic, look for libcairo2-dev, menu, force version and in the dropdown menu choose the v. from testing;

Hmm, these errors look strange. Your sources.list looks like the usual Latest repos list (only the repos are listed in reverse order for some reason ) - but where you try to install libgtk2.0-dev from? The same Latest repos or some other ones not mentioned in your message?

Did a quick install simulation (sudo apt-get -s install libgtk2.0-dev) on my system, saw no such problems with versions...
(LMDE x64, tracking Latest, Update Pack 3, neither libgtk2.0-dev nor other mentioned libs installed)

i just tried now (ok, in incoming, not latest, so may not show much) and no problems at all as well
