Update Problems
 

I am trying to update my ubuntu but I keep getting "dpkg--configure-a" ad I tried it in the terminal and it said command not found. I have tried everything and it won't work. If someone could please help me that would be great. Thanks!

dpkg I believe is used for installing .deb packages, not strictly for updates, I believe Ubuntu like Debian uses apt-get as it's primary package manager these days... could be wrong however the syntax for dpkg looks wrong, I believe it should be "dpkg --configure -a". note the spaces...
