Trying to reinstall the packages gave me an warning about broken packages. After rebooting I tried to install Firefox first in terminal. It gave me the message it was missing the hunspell-en-us packages. After having installed those, I could install and run Firefox again.
Then I tried to install Thunderbird and got this information and I do not have a clue how to fix this, as I have tried to remove earlier packages from /var/cache/apt/archives/ but keeping getting the same error:
Does anybody have an idea how to solve this? And how could I install gWaei without breaking my system?sudo apt-get install thunderbird
