Get a little more modern Redis for Your Ubuntu 10.04 LTS
Ubuntu 10.04 is still supported but that does not mean that you always want the software versions that are still supported. In contrast to Debian 6, there is no official backports repository for Ubuntu 10.04 containing a newer version of Redis than what the distribution is shipped with.
However David Murphy has made a newer redis (2.2) available for 10.04. I have only tested redis-cli so far but that did the job of connecting to newer servers, which the 2.1 in 10.04 did not.
