Ok and when i run upgrade after that it shows this error:

amirhossein@AHbook:~$ sudo aptitude upgrade
[sudo] password for amirhossein:
Resolving dependencies...
Unable to resolve dependencies for the upgrade: no solution found.
Unable to safely resolve dependencies, try running with --full-resolver.
So where is the the problem? How can i fix it?
I'm sorry if i put the topic on wrong section. Ubuntu forum is a little confusing.

Please open a Terminal from the menu Applications → Accessories → Terminal and type or better copy and paste a row atime then press enter:

gpg --keyserver keyserver.ubuntu.com --recv DD90B5460AD95754
gpg --export --armor DD90B5460AD95754 | sudo apt-key add -

sudo apt-get update

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this helps

This helped the first problem. Tnx for that. But the second one still stood.

i dont like aptitude, prefer apt-get. Copy/paste each line at a time into a terminal, then hit Enter key:

sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove

sudo apt-get update
sudo apt-get install -f

Tnx apt-get successfully upgraded. But aptitude still have the same problem.

you're right it should work, but it dont; so its up to you to make your choice :P

Well the only difference i find between these two, was aptitude is faster to type.:D

Try full-upgrade instead of just upgrade. A normal (safe) upgrade will never remove packages, but a full will. So don't proceed if it says it wants to remove lots and lots.


$ sudo aptitude full-upgrade

Also, is this a 64-bit installation?

It worked just fine! Tnx a lot. And yes. I use 64bit.

Okay.

As a slight warning; if aptitude suddenly wants to remove pretty much your whole system you may have hit bug #831768 (https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/831768).

I normally prefer aptitude because of its superior dependency resolving, but until they sort out that bug I'm falling back to apt-get.
