The software I'm using is only supported by CentOS 7.2.I tried sudo yum --releasever=7.2 updateand get Cannot find a valid basurl for repo: base/7.2/x86_64.With sudo yum updatetakes me to 7.3
How to upgrade from Centos 7.1 to 7.2?
centos;yum
CentOS 7.2 actual version is 7.2.1511 and uses this URLhttp://mirror.centos.org/centos/7.2.1511/os/x86_64/Try yum --releasever=7.2.1511 updateYou can also try to edit /etc/yum.repos.d/CentOS-Base.repo, and change baseurl to http://mirror.centos.org/centos/7.2.1511/os/x86_64/instead of http://mirror.centos.org/centos/$releasever/os/$basearch/
