@phil.davis:
That happens to me sometimes, I have systems upgrading on slow links. If a new build finishes while the upgrade is downloading, then you get the upgrade file (maybe half of it is the end of the new file?), but the sha256 checksum by then is one for the new upgrade file. It's tough after I leave a system downloading 78MB over an hour or more, ke garne? pheri koshis garnu par6 - what to do? have to try again.
Yep, that is exactly what happened. While downloading July 10 build, new snapshots of July 11 released and that could be the case. Right now I am upgrading to July 11 build.
Thanks Phil for sharing your experience.
