Talk:Help/Creating a LOTR server/@comment-35313312-20190901031240

I've gotten KCauldron.jar, and I'm trying to extract/execute it. However, it has been marked by Ubuntu (the software I'm using is Linux Ubuntu 64-bit) as unexecutable. Is there anyway to solve this, or are there any alternative softwares I'm able to use? (I plan to make a modded server with Bukkit plugins)
