Ncontrol Deb -

sudo dpkg --force-depends -i broken-package.deb Then manually install missing deps with apt . This is dangerous — use only as a last resort. For end-user applications, the best "uncontrolled deb" alternative is to avoid .deb entirely:

# Instead of manual .deb, use: sudo snap install your-app flatpak install flathub your-app These formats are containerized, update automatically, and never break system dependencies. To remove an uncontrolled package and its files: ncontrol deb

apt-mark showmanual | grep -vFf <(apt-mark showauto) But for true "no repository origin" detection: sudo dpkg --force-depends -i broken-package
