Strange dependencies problem

[RebelCoderRU]

Hi. I use Debian on my main PC and Sparky on my older, portable laptop. I installed Sparky 2 days ago and is is very nice on my older laptop. Everything works out of the box and I am thinking about switching to it on my desktop, bet there is one issue I can't solve.

I am getting constant dependencies issue i don;t see on my main Debian machine. I can't install a lot of software I need:

... and much more software would not install.

I have tried following commands:
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get autoclean
sudo apt-get update
sudo apt-get dist-upgrade

They don't help. So otherwise brilliant distro, that just picked up all of my hardware correctly, has this strange issue.
Any tips on how to fix that would be much appreciated.

Thanks.
Yuriy.

Most of your problems can be update package list related.
You tried to install: python-pivy (>= 0.5.0~v609hg-2)
by the present version is: 0.5.0~v609hg-3.1

So:

sudo apt-get update
and try again.

Hi!

I have tried all the basic things, including what you have suggested. Apt base is all up to date and the OS is up to date. That's why I asked here, as everything seems good but 50% apps have dependencies issues.

Sorry. My fault.

I have found the root of the problem. I completely forgot, that Sparky is Debian Testing based, and updated sources list to my local country but used Debian Stable. This has now been fixed.
