Ubuntu 14.04 is seriously misbehaving, and I only have access to the terminal. I propose to do a full reinstall, but want to backup the Thunderbird inbox for reinserting if it is otherwise lost in the process. This web access is from a trial version of 14.04 on DVD, and 'backups' is available. The HDD is shown on the desktop as a mass storage device, within which all the system folders appear to be accessible. What do I have to do to pull out the inbox (at least) and transfer it (or a copy) to an external mass storage device.
Thanks for any help,
