I am trying to install synapse launcher on my desktop . I am using these two commands:

sudo add-apt-repository ppa:synapse-core/ppa
sudo apt-get update && sudo apt-get install synapse

However I am getting an error with the second command saying

E: Some index files failed to download,
   they have been ignored, or old ones used instead.

I presume this has something to do with my connection to the hosting servers. But what I don't understand is the fact that synaptic is working it just seems to be something about that ppa. I don't know what I am doing wrong as the commands are widely suggested around the web, But they don't seem to work for me! I would greatly appreciate some advice on this as it is proving to be very frustrating.

Many thanks,

You're getting this error because you are using 9.10 and there don't appear to be any packages for 9.10 in the PPA.

You need to either file a bug asking them to provide 9.10 packages, upgrade to 10.04, or build from source, sorry!
