Just downloaded the latest x86_64 CentOS 7 minimal ISO from here and had no issues.
Could you please provide the output for each of the following commands:
cat /etc/redhat-release
uname -a
grep -E ^SELINUX= /etc/selinux/config
nmcli con show
ip a | grep -E 'inet\s'
ping -c 1 8.8.8.8
yum check-update | wc -l
yum info epel-release
Thank you for taking time to provide the requested information.
It appears you are attempting to install on an AltArch (32bit) version of CentOS7.
The installation script and the project team only support the _x86_64 (64bit) release of CentOS7.
While it is still technically possible to install the project on this configuration, we do not support the unofficial Special Interest Group (SIG) builds of CentOS7.
Your installation is failing due to the unavailability of the EPEL repository since EPEL does not provide a 32bit repository for CentOS7. This is only the first of many issues you will encounter..
If your system is capable of running a 64bit OS, I would highly recommend installing the officially supported release (x86_64). If you are trying to install the project on 32bit hardware, I would recommend installing Debian (Download Debian) as they provide an official 32bit install.
I will have the documentation here updated to reflect support properly.
Currently we state 'not ARM' but this should be updated to 'x86_64 only'
I actually did imagine it had to do with my OS being 32bits, but as the requisites did not specify the necessity of 64 I just went along with it. I agree, it definitely should be updated.
