前言，我对Linux很新。我在Linux服务器（Ubuntu 12.10，Quantal Quetzal）上安装了R 3.1.1（最新版本），并尝试在R中安装devtools软件包。当我运行install.packages("devtools")命令时，我收到以下内容错误：
Cannot find curl-config
ERROR: configuration failed for package ‘RCurl’
...
Warning messages:
1: In install.packages("devtools", dependencies = TRUE) :
installation of package ‘RCurl’ had non-zero exit status
2: In install.packages("devtools", dependencies = TRUE) :
installation of package ‘httr’ had non-zero exit status
3: In install.packages("devtools", dependencies = TRUE) :
installation of package ‘devtools’ had non-zero exit status
我尝试了其他相关StackOverflow答案中的所有命令（见帖子底部），但都没有奏效。例如，如果我输入sudo apt-get install libcurl4-openssl-dev，我会收到以下错误：
Err http://security.ubuntu.com/ubuntu/ quantal-security/main libssl-doc all 1.0.1c-3ubuntu2.5
404 Not Found [IP: 91.189.92.201 80]

Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
我尝试过运行apt-get update，但这也不允许我安装libcurl。
这是我的sources.list文件：

我尝试更改＆＃39;存档＆＃39;到了旧版本＆＃39;在sources.list中，但它找不到任何libcurl库：libcurl4-openssl-dev，libcurl4-nss-dev或libcurl4-gnutls-dev。
我也尝试过安装Curl 7.37.1 from source，并且安装正确。这样做允许我安装RCurl包但在尝试使用R中的install_github（）函数时收到错误：install_github('rCharts', 'ramnathv')：
Error in function (type, msg, asError = TRUE) : Protocol https not supported or disabled in libcurl
我不确定这是libcurl，RCurl，devtools还是我的旧Linux发行版的问题。不知道从哪里开始。以下是我咨询过的相关问题：
