Slow cooker, put 2kg brisket and ~120ml water in, low setting, 8 hours. Put brisket on rack, coat with a mix of tomato sauce, BBQ sauce, and mustard. Into oven at 200°C for about 20 minutes. Take it out, wrap in foil, cool until near freezing, then slice thin.
This is cheaper for 4 days of lunches than one day of takeaway for me. No nursing the food, just set a reminder and forget.
The good thing is it fails properly. This should not continue because it would break your system. The package ownership of those files has changed but the package manager would have to remove the current owning package then install the new owning package after in two separate transactions. Technically this could be make possible I think it would lead to bad packaging and would be bad practice. Happily it fails loudly and makes next steps fairly clear.
