I encountered this bug too. Here is how I was able to work around it. After using the System->Administration->Users and Groups tool to change my password, I encountered the conditions exactly as the original bug filer did under "2 - What actually happened" in his bug report.
I pressed Ctrl-Alt-F1 on my keyboard to bring up one of the non-GUI login prompts. From there, I logged in to my account using the old password. At the prompt I used the passwd command. It asked for the current password, so I gave it the old password. Then I entered in the new password and again to confirm. After that I rebooted and was able to log in with my new password. I hope that helps someone who is locked out of their system. -- 9.10 karmic gdm login fails after changing password (users-admin) when home folder encrypted (ecryptfs) https://bugs.launchpad.net/bugs/470129 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
