Xboard 怎么了？

Question

“无法安装 xboard，因为不受支持”我一个月前安装了它。两天前不得不删除它，因为命令突然不起作用（尽管鼠标操作有效）。该程序已经存在十多年了。有人修改过它吗？我在终端中收到此信息：

owner@owner-Lenovo-ideapad-110S-11IBR:~$ sudo apt-get install xboard
[sudo] password for owner: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package xboard is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'xboard' has no installation candidate
owner@owner-Lenovo-ideapad-110S-11IBR:~$

正如 Kulfy 之前在评论部分所述，所需的包可通过 universe 存储库获得。在仿生的和宇宙的如果您启用提到的源，它就是可用包列表的一部分。
