e-data-server-ui-Message: Unable to find password(s) in keyring (Keyring reports: No matching results) e-data-server-ui-Message: Key file does not have group 'Passwords-Calendar' -- evolution asking for a password, even though it should be remembered https://bugs.launchpad.net/bugs/255768 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
