And who is the "sys.admin" and does the "sys.admin"-tasks on your box ? according to this link: https://dnf-plugins-extras.readthedocs.io/en/latest/system-upgrade.html there is no explanation of 'dnf system-upgrade clean' ! so what it really does I don't know, but (I guess) it mainly removes stuff you don't need anymore ! stuff that was only necessary for the upgrade process/task. I guess mainly packages which are installed or somewhat better: the contents of these packages is copied to their target directories (see below). for 'dnf clean packages' see https://dnf.readthedocs.io/en/latest/command_ref.html#clean-command the command cleans under /var/cache/dnf/ and this directory is filled/updated (again !!!) during any run of "sudo dnf upgrade" so if you clean there there is no harm ! why ? a try of an explanation: ================== lets say you want upgrade/install a package and let's say it's name is "config.rpm". let's assume it contains mainly configuration files for the target directory /etc if you do "dnf upgrade" or "dnf install config.rpm" mainly two tasks are executed: a) config.rpm is downloaded (!) to /var/cache/dnf and b) config.rpm is installed (!), what mainly means it's contents is "copied" to it's target directory /etc after both tasks there is no need to keep the packages "config.rpm" under /var/cache/dnf/ anymore. after installation it has done it's purpose ! with other packages it works analogous -maybe other target directories are involved- Okay ? _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
