Tip on upgrading to FC 30

[ToddAndMargo]

Hi All,

If you are upgrade from 29 to 30, make sure you
update dnf and libdnf first do to a bug that has
been fixed (my procedure below takes care of this).

So far I have one virtual machine running FC30.  Haven't
got a chance to torture it yet though.

This is my update procedure:

FC 29 -->> FC 30:

# rpm --rebuilddb
# rpm -Va --nofiles --nodigest
   if anything is too new, do a
         # dnf downgrade offender(s)

# dnf --enablerepo=* update --refresh
# dnf install python3-dnf-plugin-system-upgrade
# dnf system-upgrade download --refresh --releasever=30 --allowerasing 
--best
# dnf clean packages         <-- optional
# dnf system-upgrade reboot
