无法删除 /etc/resolv.conf

今天升级到 12.04 期间，我在运行包的安装后挂钩时遇到错误resolvconf：

Setting up resolvconf (1.63ubuntu11) ...
resolvconf.postinst: Error: Cannot replace the current /etc/resolv.conf with a symbolic link because it is immutable. To correct this problem, gain root privileges in a terminal and run 'chattr -i /etc/resolv.conf' and then 'dpkg --configure resolvconf'. Aborting.

好吧，我确实尝试运行chattr -i /etc/resolv.conf，但dpkg --configure resolvconf产生了同样的错误。

我尝试手动移动或删除该文件，但即使以 root 身份也无法执行此操作：

sudo mv /etc/resolv.conf /etc/resolv.conf.old 
mv: cannot move `/etc/resolv.conf' to `/etc/resolv.conf.old': Operation not permitted

sudo rm /etc/resolv.conf                                                       
rm: cannot remove `/etc/resolv.conf': Operation not permitted

我能够（以 root 身份）在 /etc 中创建然后删除文件，因此 root 分区不会以只读方式挂载。另外：

lsattr /etc/resolv.conf
-----a--------- /etc/resolv.conf

答案1

就我的情况而言，是文件的不可变属性导致了这种情况。所以sudo chattr -a -i /etc/resolv.conf

答案2

根据帮助文件（man chattr），

A  file  with the `a' attribute set can only be open in append mode for writing.

在你的情况下，文件具有此属性

The  operator  `+'  causes  the  selected attributes to be added to the
       existing attributes of the files; `-' causes them to  be  removed;

因此要尝试的命令是

sudo chattr -a /etc/resolv.conf

并尝试再次使用列出属性

lsattr /etc/resolv.conf

然后尝试删除该文件
