try their recomendation but in a worse case scenario there is another solution (use as last case scenariio)

first off use apt for getting all your deb files it will resolve your dependency issues for you

but if apt gets hung on a loop about errors installing a file sometimes it cant overwite exsisting files etc...

cd /var/cahce/apt/archives

dpkg -i --force-all (package name)

will force it to setup said install

ive had to use this one a time or two even useing apt....
