Ubuntu 16.04-安装Apache2和Opencpu服务器时出错

Question

I'm stuck. I try to install apache, opencpu-server, R but all fails to:

opencpu-server is already the newest version (2.0.3-xenial10).
0 upgraded, 0 newly installed, 0 to remove and 7 not upgraded.
3 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

I tried to do sudo a2enmod R but it says module does not exists. I'm not really good with linux servers. Any tips?

You seem to have package conflict for apache on your system, in particular libapache2-mod-apreq2 which is a dependency of rapache. What do you see for:

sudo apt-get install libapache2-mod-apreq2

I'm guessing you have been installing packages from other repositories or some system upgrade has not gone well. You might want to apt-get purge some packages. Also check that there are no sources in /etc/apt/ that point to repositories from incorrect debian/ubuntu versions.
