 **A:** You most certainly forgot to stop and restart your server during an upgrade. The zip importer  mechanism keeps an internal cache which has trouble detecting replaced files, so a restart is needed (see TracUpgrade#ZipImportError). Do it now.

+==== Q: Attachments are missing after upgrade
+
+**A:** Most likely db28.py failed. See #11370. Please report any additional information on the MailingList.
+
+You can try to create a `run-db28.py` script:
+{{{#!python
+# -*- coding: utf-8 -*-
+#
+# Execute `do_upgrade` in trac/upgrades/db28.py
+#
+# Usage: python run-db28.py /path/to/tracenv
+#
+
+from __future__ import with_statement
+
+from trac.env import Environment
+from trac.upgrades import db28
+
+def main(args):
+    for arg in args:
+        env = Environment(arg)
+        with env.db_transaction as db:
+            cursor = db.cursor()
+            db28.do_upgrade(env, 28, cursor)
+
+if __name__ == '__main__':
+    import sys
+    main(sys.argv[1:])
+}}}
+
+And then apply it to the broken environment:
+{{{
+> python rundb28.py /path/to/broken/environment
+}}}
