The latest Password Safe Beta for Linux (committed February 8, 2015), now installs cleanly on Fedora 21.
Password Safe 0.95.1BETA-3 rpm (pwsafe-0.95.1BETA-3.x86_64.rpm), available here, can be installed on Fedora 21 once the following packages have been added to the system using yum:
wxGTK3 (installs wxBase3 as a dependency)
ykpers (installs libyubikey as a dependency)
Those who don’t want to mess with creating .desktop files and symlinks may prefer this package to the Java SWT version described below (I know I do).
