Question: How to install NCDU on Scientific from EPEL?

Your approach looks correct in terms of setting up the EPEL repository and attempting to intsall NCDU. I even confirmed that hte NCDU RPM is in fact in that repository:

So this particular issue looks like it has little to do with the RPM, and more to do with the setup of the EPEL repository on your system.

The quick answer

If you just want to install NCDU you can simply do this to manually install the RPM from that repository:

$ sudo yum localinstall \
    http://ftp.linux.ncsu.edu/pub/epel/6/x86_64/ncdu-1.7-1.el6.x86_64.rpm

The long answer

If you'd like to figure out what's wrong with your YUM setup I'd first start with running the command yum clean all.

After that I'd double check that the .repo files for the EPEL repo are in fact setup correctly undre /etc/yum.repo.d/.

I'd also remove and re-install the EPEL RPM file:

$ sudo yum remove epel-release
$ sudo yum localinstall epel-release-6-8.noarch.rpm
  • Executing ncdu after installing http://ftp.linux.ncsu.edu/pub/epel/6/x86_64/ncdu-1.7-1.el6.x86_64.rpm results in ncdu 1.7 ~ Use the arrow keys to navigate, press ? for help. Thank you.
