When removing packages with yum or dnf, pass the --disablerepo=* (disable all online repositories) and -C (run from cache) arguments. Package removals do not normally require network access, and this measure saves time and bandwidth and prevents possible unnecessary errors (e.g., if we do not have active network access, or if there is some problem with the mirrors).
