Hello, this page: https://pharo.org/gnu-linux-installation
1) in examples, there is a usage of "yum-config-manager" command, add a note that "yum-utils" package must be installed 2) correct all paths to the opensuse repos please, at least this is wrong: CentOS 7 (only 64bit): http://download.opensuse.org/repositories/devel:/languages:/pharo:/stable/CentOS_7/devel:languages:pharo:latest.repo Correct URL is probably: http://download.opensuse.org/repositories/devel:/languages:/pharo:/stable/CentOS_7/devel:languages:pharo:stable.repo pf
