I have followed the steps in the similar thread.
sudo wget -O /etc/yum.repos.d/slc6-devtoolset.repo \ http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo
this I think worked fine, then
sudo yum install devtoolset-2
which failed with the error:
warning: rpmts_HdrFromFdno: Header V3 DSA/SHA1 Signature, key ID 1d1e034b: NOKEY Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern
Indeed this file is not in
on my computer. Am I supposed to get the file from somewhere and put it there by "hand"?
