请教： OK3568开发板如何安装cutecom？

ARMer

您好，我在开发板的forlinx desktop 上安装cutecom图形化串口工具；

forlinx@ok3568:~$ sudo apt-get  install cutecom
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package cutecom
forlinx@ok3568:~$


提示没找到安装包， 请问Forlinx有没有可以apt-get使用的sources.list?
或者其它安装方法？

我在开发板上apt-get install 从来没成功过，虽然已经用了阿里、清华等国内的list，不知为何就是不行。

这个cutecom是源码要用cmake编译，开发板好像不行，头疼~~:dizzy:

多谢！！！

forqs

先sudo apt update更新下软件包列表再sudo apt-get  install cutecom。
