Confirmed in Xubuntu 12.10. Leaving out the brackets does not solve the issue. I thought this was an issue with special characters however:
Composing a password exclusively from special characters works fine... E.g., !@#$%^&*()_+ Adding a regular character to the above string is also fine but the second regular character triggers the bug. !@#$%^&*()_+1 = 'Strong password' !@#$%^&*()_+11 = 'Short password' And as the original submitter mentioned any strong password that becomes 'short' will fail to unlock the volume with the error: 'cryptsetup: cryptsetup failed, bad password or options?' ** Tags added: cryptsetup failure installer ubiquity -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1080445 Title: Lubuntu full disk encryption password quality check on installation is confused by ( To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1080445/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
