Looks like you have a missing or bad disk. However, without knowing more about your system, it will be difficult to suggest a *proper* solution. Could you [edit] your question to include: (0) the version of Ubuntu you're running (1) the contents of `/etc/fstab` (2) the Terminal output of `lsblk`. With this, it *might* be feasible to suggest a way forward.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
