we spent an hour walking around the grocery store, however, lucas sinclair did not find a single snack that he liked.

Explanation:

The word "however" is a conjunctive adverb used to show contrast between two independent clauses. When it appears between two independent clauses, it should be preceded by a semicolon and followed by a comma. The original sentence uses a comma before "however", which is incorrect. So we replace the first comma with a semicolon.
