@Scion This will happen if the download was incomplete or corrupted. From the looks of your screenshot, the sha1 check may have happened before the download was completed. My question is if this is repeatable? Does it happen every time you try to upgrade zulu?
I’m going to go out on a limb here. I host many, many, of these in the cloud. I bet this would occur on at least 90% if I ran that command from CLI at this point. BUT! The good news is, Zulu and I had a great battle in the past and I have moved on. I have not tried to delete the cached files yet because, I simply don’t care. I just hope this isn’t a issue for Zulu reliant folks.
