Hello my friends,

I would like to thank you all. In fact you are right, 'libcurb3' was all the time there in extras-devel repository and couldn't see it simply because it was installed with its last update on my tablet N900.

Now the question is why i couldn't still share on FB like before? Because when it was updated, i had since a long time an annoying error message telling that i cannot uninstall 'catblock' and i don't know why i went through the forum to look for the solution and I succeeded to uninstall 'catblock'. That was the problem, after uninstalling 'catblock' i tried from the command line to install libcurb3 and it returns that it is already installed in its last update then i shared a photo on FB and it is working as before.

So again thank you all for your support.
