求助apt-get安装jdk1.6失败

[z99677273]

sudo apt-get install sun-java6-jdk

Package sun-java6-jdk 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 sun-java6-jdk has no installation candidate

查出来原因是找不到合适的源
但是网上找到的几个使用率高的源，我试了下都ping不通
archive.canonical.com
archive.ubuntu.com
mirrors.163.com

找找能用的源吧，如中科大的
