update-alternatives --install says it needs link name path priority?
Are you leaving a space between the -- and the word install? if so, don't - it needs to be --install
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0.05/bin/java 1
The quotes should not be necessary since none of the elements have embedded spaces - although they shouldn't do any harm.
The command sintax is
sudo update-alternatives --install <link> <name> <path> <priority>
if there are no space in the parameters, you don't need quotes.
In your case:
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0/bin/java 1
Pay attention: did you really have a space in the path before jdk?
This is beacause this command maintains symbolic links. I recommend to execute man update-alternatives
to get more information about the command.
