As you may know, KeePassX is an open source application used for password-management, enabling the users to create, store, generate and edit passwords. It encrypts the passwords and databases via the AES or Twofish algorithms, providing security for the user’s passwords.
The latest version available is KeePassX 2.0.0, which has been released a while ago.
Up to date packages are available via Eugen San’s PPA, so installing the software on Ubuntu is easy. Just add the PPA to your system, update the local repository index and install the keepassx package:
$ sudo add-apt-repository ppa:eugenesan/ppa
$ sudo apt-get update
$ sudo apt-get install keepassx
Optional, to remove keepassx, do:
$ sudo apt-get remove keepassx
