sudo echo 'deb http://www.duinsoft.nl/pkg debs all' >> /etc/apt/sources.list
sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 5CB26B26
sudo apt-get update
sudo apt-get install update-sun-jre
exit
但是当我这样做的时候
sudo echo 'deb http://www.duinsoft.nl/pkg debs all' >> /etc/apt/sources.list

问题没有解决,我仍然看到权限错误,我在64位笔记本电脑上
解决方法:
这是一个众所周知的问题,当你以这种方式使用sudo时,它将无法正常工作.这是因为当echo命令以sudo运行时,>> for append尝试以非sudo用户身份打开文件目标.这是许可问题所在.
但是,请阅读我的两部分答案,这给你一个单独的解决方案(有点)：
1：
在/etc/apt/sources.list.d/中使用单独的文件,其中包含您现在要说的deb指令.但是,你仍然需要使用sudo来编辑/创建文件.
2：
一个解决方案是做sudo su -c“echo’deb http://www.duinsoft.nl/pkg debs all’>> /etc/apt/sources.list”,告诉系统将其运行为超级用户,您可以通过在’su’命令前使用’sudo’来访问它.
请注意,在我所说的命令之外使用的su命令是危险的,所以如果你绝对需要它,你应该只使用这种方法.
