以前我可以使用'sudo aptitude install'命令来安装软件。 今天当我试图安装rkhunter我得到错误。 这不仅仅是呃，我不能安装任何东西。
这是文本输出：

问题发生在dpkg想要解压*.deb文件，可能是一个文件系统挂载选项的问题：
这是错误：
unable to create `/usr/bin/lsof.dpkg-new' (while processing `./usr/bin/lsof'): Permission denied
你可以在没有ro选项的情况下挂载文件系统吗？
提示 ：
mount / -o remount,rw
如果/是你的挂载点（可能是/usr/bin所属的任何地方），可能是/usr/
/ dev / sda1 on / type ext3（rw，noatime，errors = remount-ro）

有问题的软件包位于软件包caching中。 尝试这样做：
sudo apt-get clean
另一个潜在的问题是安装点可能已满。 你尝试过做一个df ？
