This is similar to another thread I started here.  IMHO
upgrades are the scariest part of Linux.  I always take
full backups of everything first with a script like this:

#!/bin/bash
# Back up cjglap2 - version 2025-08-27
# This script must be run as root!
if [ "$(id -u)" -ne 0 ];
then
  echo This script must be run as root!
  exit
fi
# Copy the root partition.
dd if=/dev/sda1 | gzip >/mnt/backup/cjglap2/sda1.img.gz
# Copy various directories.
rsync -av --delete /etc                                /mnt/backup/cjglap2
rsync -av --delete /usr                                /mnt/backup/cjglap2
rsync -av --exclude='/home/cjg/.cache/' --delete /home /mnt/backup/cjglap2
rsync -av --delete /var/spool/slrnpull                 /mnt/backup/cjglap2

Then, even if the worst happens, I can wipe the disk and start over.
Having /home in its own partition makes things a lot easier.
