How to upgrade from Fedora33 to Fedora34 with less stress.

Upgrade "By the book" instructions:

Update software and back up your system.
dnf upgrade --refresh

Install the DNF plugin.
dnf install dnf-plugin-system-upgrade

Start the update with DNF.
dnf system-upgrade download --releasever=34

Reboot and upgrade.
dnf system-upgrade reboot

Now let's fix the problems.
must resolve all .rpmnew and .rpmsave files rpmconf -a

must run hp-setup again to detect scanner
hp-setup -i

Terminal and Nautilis Menu Bar needs color
Tried this:
To file /home/.config/gtk-3.0 Add:
.titlebar:not(headerbar) {
background-image: none;
background-color: @theme_bg_color;

It doesn't work. No color in the menu bars!
Alacarte gets uninstalled, appeditor is supposed to replace it

Fedora install no longer asks for root password.
To change the root password type:
sudo passwd root

Get rid of Activities Menu leaving only Applications and Places
dnf install chrome-gnome-shell
DOES NOT WORK, hangs system.

Reinstall instead of Upgrade instructions:
If you are forced to reformat any disks:.
/boot must be on ext4 and one giga!
/boot/efi must be fat16 Efi system partition and 200 mega.
/ and swap; I used lvm 120 giga.

Samba could not connect from the outside.
Firewalld was install by default.
Stopped, Disabled and returned to iptables!

DANGER - iptables does not run automatically anymore. It was changed to iptables-legacy.
You need to convert to nftables and enable and start that service or you are unprotected!
They don't tell you this and you could be running your system for months before you find out!

/bin/bash /etc/rc.d/rc.firewall
iptables-save >/tmp/iptables.dump
iptables-restore-translate -f /tmp/iptables-dump >/etc/nftables/firewall.nft

nft list ruleset
