Installing Keepass2

I’m new to Netrunner and linux in general. I am trying to install keepass2 with no success. I searched all the sites in internet but none worked. I tried with Muon but get the message - The package system could not be initialized, your configuration may be broken. In details it writes - unable to correct problems, you have broken packages.
Can anyone help?

This normally means that the dependency for keepass2 could not be found. So either you have a half-installed keepass2 or the package you found is not compatible with your Netrunner system.
