I'll leave neutral karma, but arduino "ide" doesn't start, nothing happens, if you execute it manually /usr/bin/arduino Error: Could not find or load main class processing.app.Base
arduino-1.6.4-2.fc23.noarch arduino-doc-1.6.4-2.fc23.noarch arduino-core-1.6.4-2.fc23.noarch
I tested removing package before this update, package was a dependency for other package, it failed (just like in bug report). After installing this package from koji, I was able to remove same package, it asked to remove other package depending on it. Everything looks OK.
tested manually installing dep, fixes the problem, then did yum history undo... later tested this package from koji, "Installing for dependencies: socat", and pam-kwallet opens kwallet. Fixes bug #1155873 for me
