But as a guess, one thing that sometimes causes a stall near the end of "enumerating objects" is loosening unreachable objects that are currently packed. You told repack to use "-A", which asks to loosen those objects so they aren't lost when the old packs are deleted (as opposed to "-a"). You'd probably want to at least say "--unpack-unreachable=some.time" to avoid writing out ones which are not even recent (and which is what "git gc" will do under the hood). But if you don't care about keeping them at all (e.g., because this is not an active repository where other simultaneous operations may be taking place, so you know it is safe to delete even recent ones), then just "git repack -a -d" is probably your best bet. -Peff
