Some good old phone images that are hard to find online, but they are very old and do not receive updates!!
When I checked, the ROM is also on https://lineageosroms.com/i9300/ with the same hash (you probably want to check it), so can download from there instead.
The zip is on git-lfs, get withsudo apt install git-lfs
and then clone the repo.
