Using apt-get to install solr-jetty only gives me version 1.4 of Solr, but I would like to use one of the 3.x versions.
I'm not yet confident enough to do a manual installation (something usually goes wrong or I end up irreversibly breaking something).
Is there a way I can easily install the version of solr-jetty for I want for my version of Ubuntu via apt-get?
As an update to the question, I have tried the PPA in the suggested question, however, it did not work. I am told that this is because it is for a different version of Ubuntu.
This is the error I receive at the end of running apt-get update:

E: Some index files failed to download. They have been ignored, or old ones used instead.
I have also tried an installation of Jetty and Openjdk using apt-get, but this resulted in Jetty not starting as a service.
