A decided to repeat the command “php /tools/upgrade.php patch”. It failed too because the whole site was in fact in the new version but the database was in the older version. I turned off the website as it shows the readme file and then I upgraded the site.
The web looks like always with no problems but I’m concerned about this “failed to apply patch”…
If you haven’t made many local customizations to the code, I would strongly recommend following the “Full Package” upgrade instructions just to ensure that your codebase is in line with the current release.
Alternately, consider comparing your install to a clean codebase to identify any wanted/unwanted code changes:
I have not reviewed the live website - it would be difficult to detect nuanced changes just in perusing the public pages.
With local code customizations, I still strongly recommend @asmecher’s suggestion of comparing your codebase against a clean codebase to ensure only desired code changes are in place. The message “failed to apply patch” indicates that you changed code at or near some upstream changes for the new version.
The only way to be sure is the compare the code, preferably cataloging your local changes in some form of version control, such as Git or Subversion.
