Thread:Talk:Release notes/1.23/Patch to previous version (1.23.3) is not working/reply

The problem is caused by the install being from a tarball while the patch is based on an installation from Git. Files for testing purposes aren't included in the tarball, but patch tries to change one of them, which is why it fails. The upgrade from 1.23.3 to 1.23.4 is successful despite breaking out of it at the error with Ctrl-C. It's only the missing file that gets skipped. See bug 71379
