No, dont worry. I thought I'd help you fix it since this thread will probably stay as a reference to others with the same problems. Anyway seeing that error I'm guessing you typed: dpkg -/home/user/MyDocs/fmtx-faker_0.1_armel.deb When what you should type is: dpkg -i /home/user/MyDocs/fmtx-faker_0.1_armel.deb "dpkg" is the package manager command. "-i" means to install something. and the path and filename is what to install! You see small typing errors can have huge impacts in the world of linux and unix. Which is why I asked you to first of all check the spelling and cases.
