Ubuntu 16.04 LTS was damaged during an upgrade and it can't be fixed. I need to save all my files in the disk in another disk.
When I log in as root during recovery mode, I see all my files there and I can read them without issue.
However when I connect a new disk (usb or hard disk) via USB this is not visible in the media folder, therefore I have no way to copy the files somewhere else, what should be done so that I can connect an external disk and copy all the contents that I need into the other disk?
