Citat af Reindl Harald <h.reindl@thelounge.net>:

just use "dnf --releasever=23 distro-sync" and forget about this stupid offline-updates, recently upgraded more than 20 servers *online* that way which where originally installed 2008 with Fedora 9 long before some unix youngsters started to make the windows mistakes on Linux

Command used to upgrade: *dnf system-upgrade download --releasever=23*

And it is not an option to use '--allowerasing' or to set packages touser installed
