It should work with no problems, but remember: You do that on your own risk!
To make dist upgrade from Sparky 6 to 7 do:
1. Backup your personal files to external disk or partition.
2. Change Debian repositories from bullseye to bookworm at the file:
/etc/apt/sources.list
So it should look like that:
deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware deb http://security.debian.org/debian-security/ bookworm-security/updates main contrib non-free non-free-firmware deb-src http://security.debian.org/debian-security/ bookworm-security/updates main contrib non-free non-free-firmware deb http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware deb http://deb-multimedia.org/ bookworm main non-free
3. Change Sparky repositories from potolo to orion 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/ orion main deb-src [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ orion 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
