One of your local mirrors listed in /etc/apt/sources.list.d/*.list or /etc/apt/sources.list probably uses https (not a very common scenario for package mirrors), in which case you need the package mentioned above (apt versions below 0.9.15.3 fell back to plain http, if https was unavailable).
Line a broiler pan with aluminum foil, add the top, and spray the top with nonstick cooking spray. Broil the steak 4 to 6 minutes per side: Remove the steak from the marinade, shake off any excess, and place it in the middle of the broiler pan. Slide it directly under the broil. Cook for 4 to 6 minutes, flip it over, and broil for another 4 to 6 minutes (8 to 12 minutes total). Check the steak for doneness: The steak is done when the edges are charred and crispy, and you see some nicely dark searing on the top.
The next step is to put the flank steak on the grill. Itâs recommended that you then grill the steak for approximately 10 minutes over coals that are medium-hot. While a grilling time of 10 minutes will give you a medium-rare steak, you may allow it to grill for a bit longer until the beef reaches the desired doneness.However long you decide to grill your flank steak, remember to turn it over as soon as the grilling time is halfway done.hile a grilling time of 10 minutes will give you a medium-rare steak, you may allow it to grill for a bit longer until the beef reaches the desired doneness.
