Comment 0 for bug 1015692

Upon upgrade from 12.04 to quantal, my offlineimap configuration broke, showing messages like:

| *** Processing account Gmail
| INFO:OfflineImap:*** Processing account Gmailu
| Establishing connection to imap.gmail.com:993
| INFO:OfflineImap:Establishing connection to imap.gmail.com:993
| ERROR: Server SSL fingerprint 'f3043dd689a2e7dddfbef82703a6c65ea9b634c1'
| for hostname 'imap.gmail.com' does not match configured fingerprint.
| Please verify and set 'cert_fingerprint' accordingly if not set yet.
| INFO:OfflineImap:ERROR: Server SSL fingerprint 'f3043dd689a2e7dddfbef82703a6c65ea9b634c1'
| for hostname 'imap.gmail.com' does not match configured fingerprint.
| Please verify and set 'cert_fingerprint' accordingly if not set yet.

The fix is for the user to add an entry for 'cert_fingerprint' in the same spot as 'ssl = yes' (which is automatic if 'type = Gmail').
Ie add:
 cert_fingerprint = f3043dd689a2e7dddfbef82703a6c65ea9b634c1

So that your Repository entry looks something like:
| [Repository GmailRemote]
| type = Gmail
| # ssl = yes # this is default for gmail
| cert_fingerprint = f3043dd689a2e7dddfbef82703a6c65ea9b634c1
| remoteuser = <email address hidden>

There is some discussion at http://comments.gmane.org/gmane.mail.imap.offlineimap.general/5654 about possibly using system certificates to make such manual configuration unnecessary.
