md5 checksum?

posts: 80 United States

I'm noticing quite a few bugs in my upgrade from 1.9.7 to 2.2. I'm pretty sure I followed the instructions correctly, but it occurred to me that I never did an md5 checksum on the downloaded file. Is that obsolete? I don't seem to find instructions or the appropriate checksum file anywhere.

This is not a criticism. I'm trying to figure out how to be sure that the file I downloaded and then uploaded again to my webhost is intact. If it isn't, that could be the source of the bugs I am seeing. This used to be done by checking an md5checksum file. I'm not sure that's still the way it is done.

Let me know.

This hadn't occurred to me either until I was having a problem with an installation and then I thought perhaps the cause of the, as yet undiagnosed problem, was a corrupt installation.

As I understand it, MD5 is not foolproof, but I would think it is good enough for validating that a file has downloaded without errors.

I guess the only thing you can do is scan the downloaded the archive for errors, although some errors might not show up in such a scan.

Good point this. MD5 hashes get my vote.
