dkpg: command not found

Hi, I've installed Jaunty with KDE3.5 and I'm encountering the following problem. Even though dpkg is installed (if I launch 'dpkg' in the konsole I get the help text), when I try to use the command to install a package ('dpkg -i packagename.deb') I get the following error: bash: dkpg: command not found This happens both with or without sudo before the command, so it's not a problem of permissions. 'locate dpkg' outputs '/usr/bin/dpkg' but even if I launch '/usr/bin/dpkg -i packagename.deb' I get the same error! Any suggestions? Thanks Luca
