I use Codelite extensively, for software development. However, the version of Codelite available in the Ubuntu/Debian repositories are a bit old. Our recent upgrade to Trusty Tahr 14.04 LTS resulted in a buggy Codelite that keeps crashing. As a result, it was time to upgrade.
So, we upgraded Codelite following the instructions on their site.
sudo apt-key adv --fetch-keys http://repos.codelite.org/CodeLite.asc
sudo apt-add-repository 'deb http://repos.codelite.org/ubuntu/ trusty universe'
sudo apt-get update
sudo apt-get -y dist-upgrade
That did it.
