我已经从 Ubuntu 12.04LTS 升级到 14.04LTS。我的 WiFi/蓝牙卡是 ralink。当我安装无线驱动程序时,barracuda ppa 被添加(未选中),我按如下方式启用(选中)它们:
现在,问题是当我跑步时
sudo apt-get update && sudo apt-get install build-essential linux-headers-generic
在终端输出如下:

哪里有问题?
答案1
该 PPA 不适用于“Trusty”,仅适用于“Raring”。
尝试将分发版中的“trusty”替换为“raring”。只需在“软件和更新”(您的图像)中选择 PPA,然后单击“编辑...”,并在“分发版”下写入“raring”(不带引号)。对“源代码”PPA 也执行此操作。
在那之后
sudo apt-get update
并安装您需要的。您安装的所有东西可能都能正常工作,但不保证。
