"Attachment missing after upgrade" qualifies as a FAQ

 **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 `rundb28.py` script:
+{{{#!python
+#!/usr/bin/python
+from __future__ import with_statement
+import sys
+from trac.env import open_environment
+from trac.upgrades.db28 import do_upgrade
+
+env = open_environment(sys.argv[1])
+print 'Fixing attachments for environment', env.project_name, 'at', sys.argv[1]
+with env.db_transaction as db:
+        cursor = db.cursor()
+        do_upgrade(env, None, cursor)
+        db.commit()
+}}}
+
+And then apply it to the broken environment:
+{{{
+> python rundb28.py /path/to/broken/environment
+}}}
