Answer:
4 2 6 1 7 or 1 2 4 3 7
Step-by-step explanation:
4 are correct of 1,3,4,6,7
3 are correct of 0,2,3,6,7
1 is correct of 0,3,6,8,7 -- so not both 3 and 6, meaning 1, 4, 7 are correct
Correct digits so far are 1, 4, 7 and one of {3, 6}. Line 2 tells another is 0 or 2; line 3 tells it is not 0. This adds 2 to the list of correct digits.
This makes the correct digits 1, 2, {3, 6}, 4, 7. We don't know whether the last digit is 3 or 6.

Looking at digits correctly placed, line 2 tells us the code is either ...
_ 2 6 _ 7 or _ 2 _ 3 7
Then line 1 fills in those blanks as ...
4 2 6 1 7 or 1 2 4 3 7
Either of these codes agrees with all of the clues.
