我买了一台装有 Ubuntu Bionic Beaver 的新笔记本电脑。我想安装 Tremulous 来玩，但安装程序失败，我找不到适合我系统的任何软件包。
bash tremulous-1.1.0-installer.x86.run
Verifying archive integrity... All good.
Uncompressing Tremulous

./setup.sh: 201: ./setup.sh: /home/#####/.setup2976: not found
The setup program seems to have failed on amd64/unknown
Fatal error, no tech support email configured in this setup
我如何安装该游戏？
