Seamonkey

[valtam]

Where did you download seamonkey from originally? I don't recommend using software outside of what Synaptic provides, it's a minefield out there and can land you in these kind of situations. Open a terminal and type:

Code:

sudo apt-get -f install

If your original download was a .deb file. The above command should give you the additional packages you need to run seamonkey.

or do as rokytnji suggested if you got the download from here - http://www.seamonkey-project.org/releases/

Is there any reason why you need seamonkey specifically?
