I have a problem with my Linux OS (Ubuntu), I was working normally, and suddenly I couldn't do anything, the files on my home were disabled, after the restart, the OS booted up, but not the graphical server, it displayed this message:

I have 2 disks, a mechanical (sda) and solid (sdb), My OSs are in sdb and I use my old disk (sda) for file storage.

The partition of linux is sdb5, and my /home is sdb6. The details of this command is in: https://pastebin.com/2MzYWHr0

When I did

systemctl -xb

And some of the relevant messages were:

I realize is that the /home partition is not mounting.

I do these steps to start my graphical server:

  1. Execute: systemctl reboot
  2. Log in with the root account again (because after systemctl reboot, it asked me again for root).
  3. Execute: mount -t ext4 /dev/sdb6 /home/
  4. Execute: systemctl default

I have to manually mount the /home partition. After this the graphical server starts and I can work normally, just that I get a message of an error report, besides that, everything appears to work normally.

You've not provided any release details; and your mention of Server (therefore no GUI) and Graphic Server is somewhat confusing (if you add a desktop to a server system, it's converted into a desktop system usually though depends on details you've not provided, but will still perform server functions). Your issue appears to be an altered *file-system table* (`fstab`), I'd suggest checking that on your *unstated* Ubuntu product.

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.
