It should work with no problems, but remember: You do that on your own risk!
To make dist upgrade from Sparky 7 to 8 do:
1. Backup your personal files to external disk or partition.
2. Change Debian repositories from bookworm to trixie at the file:
/etc/apt/sources.list
So it should look like that:
deb http://deb.debian.org/debian trixie main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian trixie main contrib non-free non-free-firmware deb http://security.debian.org/debian-security/ trixie-security/updates main contrib non-free non-free-firmware deb-src http://security.debian.org/debian-security/ trixie-security/updates main contrib non-free non-free-firmware deb http://deb.debian.org/debian trixie-updates main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian trixie-updates main contrib non-free non-free-firmware deb http://deb-multimedia.org/ trixie main non-free
3. Change Sparky repositories from orion to sisters at the file:
/etc/apt/sources.list.d/sparky.list
So it should look like that:
deb [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ core main deb-src [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ core main deb [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ sisters main deb-src [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ sisters main
4. Refresh package list:
sudo apt update
5. Dist upgrade now:
sudo apt full-upgrade
If any problem run:
sudo dpkg-reconfigure -a sudo apt install -f
