Hi bitsnpcs,
You can remove those PPA's you don't need from the repository
sudo add-apt-repository --remove ppa:ubuntuhandbook1/ppa
sudo add-apt-repository --remove ppa:jon-severinsson/ffmpeg
sudo add-apt-repository --remove ppa:rvm/smplayer
sudo add-apt-repository --remove ppa:noobslab/apps

then run this command:
sudo apt-get update
That with steam, might be a temporary error at the server. If you still have problems with that post it here.
