You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
openssh-client: Depends: openssh-common but it is not going to be installed
openssh-server: Depends: openssh-common (= 1:5.1p1-6.maemo5) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

what repositories do you have enabled ?

did you try apt-get -f install ?
if so what's the output

thX "ivyking"
The repositories that i have enabled are : fremantle ssu apps, fremantle ssu mr0, fremantle1.2 ovi. --> i'am not sure but i think that they have been enabled after that i made the update.
and yes i tried apt-get -f install and this is what i get ! :

i had the same problem,tried asking around but no one seemed to have a clue::..so i just reflash my phone::..gd luck

You have to enable some other repositories. This is my repo.list:

Thanks but i have already enabled all those repositories !

But please if anyone knows any other solution, because i do not want to reflash it !
thanks you

Then why didn't you list them when you were asked what repositories you have enabled?

What's the output from running "apt-get update"?

apt-get update --fix-missing

May help? But enable all repo's.

it seems from the looks of things that you don't actually have extras-devel enabled, however wrt-api exists there only for now..

so either enable extras-devel and then update the repositories and try again (easiest, recommended)

or download the package manually to your n900 from here

http://maemo.org/packages/package_in...wrt-api/1.1.0/

either using the browser, then using application manager to install

or do the following

cd /home/user/MyDocs/
wget http://repository.maemo.org/extras-devel/pool/fremantle/free/w/wrt/wrt-api_1.1.0_armel.deb
sudo gainroot
dpkg -i ./wrt-api_1.1.0_armel.deb
apt-get install openssh-client openssh-server

in case you get errors about unmet dependencies you will need to download them as well, to get a package directly, search google with the following :
maemo package <packagename>

so my suggestion is instead of all this, simply enable extras-devel repository, update the repos, install openssh as needed then disable extras-devel again if you want (recommended).

From the terminal did you try "apt-get -f install (xxxx)"

xxxx = each dependance separately?
