How to upgrade from Fedora34 to Fedora35 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=35

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 192.168.90.10

Terminal and Nautilis Menu Bar needs color
Tried this:
To file /home/.config/gtk-3.0 Add:
headerbar {
padding: 0 6px;
min-height: 46px;
border-width: 0 0 1px;
border-style: solid;
/* border-color: @border_color; */
background: @theme_bg_color linear-gradient(to bottom,
shade(@theme_bg_color,1.2),
shade(@theme_bg_color, 0.8));
box-shadow: inset 0 1px rgba(255, 255, 255, 0.8);
}

headerbar:backdrop {
background-image: linear-gradient(to bottom, shade(@theme_bg_color,1.2), shade(@theme_bg_color, 0.8));
box-shadow: inset 0 1px rgba(255, 255, 255, 0.8);
transition: 200ms ease-out;
}

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

Tweaks no longer controls Applications and Places menus.
dnf install chrome-gnome-shell
https://extensions.gnome.org/extension/

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.

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

test:
iptables-save
nft list ruleset


DANGER - php8.0 gets installed
Older Joomla, Craft and WordPress sites will not work - blankscreen!
You ma need to install php 7.4 fromthe remi repo!

DANGER - dnf upgrade overwrites your /etc/resolv.conf with a useless file that blocks sendmail from receiving mail!
/run/systemd/resolve/stub-resolv.conf
restore your original /etc/resolv.conf
