The sparky's linux packages in TESTING changed their suffix from 'sparky8' to 'sparky' so, to get updating the sparky latest, 6.12-lts and 6.6-lts kernels, simply uninstall sparky kernels with 'sparky8' suffix and install it back with 'sparky' suffix. Anyway, the sparky linux kernel packages have been separated from core repos to their default (named) repos now. It lets me easy configuration in aptus and therafore, added to sparky-package-tool now #linux #debian #sparkylinux
