我有ubuntu 14.04，我无法在R 3.0.2上安装XML包，当我点击
install.packages("XML")
我得到了回来;

Warning in install.packages :
installation of package ‘XML’ had non-zero exit status
The downloaded source packages are in
‘/tmp/RtmpySPbSU/downloaded_packages
为此我得到了我应该安装xml2-config的东西，但是当我尝试我得到它;

Warning in install.packages :

我也试过安装那些：
> install.packages("libxml2-devel")

我认为3.0.2是最新的R版本，我不认为它说我需要一个使用XML的软件包，它无法在R 3.0.2中实现
我已经在这里尝试了解决方案;
Unable to install R package in Ubuntu 11.04
我得到了这个
Reading package lists ... Done
Building dependency tree
Reading state information ... Done
Might want to run 'apt-get f install' to correct these:
The following packages have unmet dependencies:
libreoffice-core: Depends: libreoffice-common (> 1: 4.2.4) but it will not be installed
libreoffice-help-en-us: Depends: libreoffice-l10n-en-us
libreoffice-l10n-en-gb: Depends: libreoffice-common but it will not be installed
libreoffice-l10n-en-za: Depends: libreoffice-common but it will not be installed
libreoffice-l10n-en: Depends: libreoffice-common but it will not be installed
E: Unmet dependencies. Try 'apt-get f install' with no packages (or specify a solution).
如果我输入“apt-get -f install”，它就无法工作，我得到了这个;
E: Could not open lock file '/ var / lib / dpkg / lock "- open (13: Permission denied)
E: file replica "/ var / lib / dpkg / 'was not found
