[Answered] Upgrade to 4.2.1 Error - found 4.2.1, expected 4.2.0 Patch Level 2 - WTF?

[John h]

I uploaded 4.2.1 files to my server and went to upgrade I get this error:

Due to the following errors, the install/upgrade can not continue:

    Following is a list of files that are either missing or contain unexpected contents. The most likely cause is that all of the files from this release have not been properly uploaded. You should resolve this error before continuing.

Ok, I am trying to upgrade to 4.2.1, why should the upgrade script expect 4.2.0 Patch Level 2???

I uploaded the files again, but get the same result?

[John h]

ok, it looks like it was an file upload problem. I ended up zipping the files, uploading the zip and extracting the zip on the server using the cpanel file manger tool.

[Hartmut]

Maybe the upload mode was incorrect.
