Thanks for your report.

Ah, dpkg -P fails when facing dependency issues. Anyway I think we should not use this, but G_AGP (apt-get purge) instead, which calls APT with options to purge all dependants as well and skip non-existent packages.
Switch to dpkg -P initially due to: https://github.com/Fourdee/DietPi/commit/1aa2cbed70bd57226103799c7287143c3b0ae079
🈯️ G_AGP with non-repo package works well on Stretch
🈯️ And Jessie

Fix is done for v6.17: https://github.com/Fourdee/DietPi/commit/0cf17fa913f7860c073f18355e2f1c86eb230a25
