I am running WordPress 2.7.1 on a Godaddy-hosted Linux server. When I run their "automatic upgrade" to 3.5, I get the following:
Downloading update from http://wordpress.org/wordpress-3.5.zip
Unpacking the core update
Verifying the unpacked files…
Warning: copy(/home/content/n/e/d/nedbj2/html/blog/wp-contentupgrade/version-current.php) [function.copy]: failed to open stream: No such file or directory in /home/content/n/e/d/nedbj2/html/blog/wp-admin/includes/class-wp-filesystem-direct.php on line 122
Could not copy file.
Notice that the path to the missing file seems to be missing a '/' between "wp-content" and "upgrade'. Although this may be an error in the error messages itself, it seems more likely that it is a problem in the underlying script. Also, I looked in the correct "version-current" directory (which is there) and it is completely empty.
Even if I found a way to fix the missing '/' I would presumably still have a problem with the file that is actually missing in the version directory. It would be easy to fix that, if I knew the format it expects inside that file.
I looks like there is just too great a jump from 2.7.1 to 3.5. I have considered upgrading in stages, say to 3.x and then to 3.5. Does anyone have any answers or recommendations? Thanks.
