Ubuntu 20.04 gets stuck in the login loop

I can open the desktop using startx command in other tty

I have tried a lot of methods:

  • chown the Xauthority file
  • chmod the /tmp
  • check the /etc/environment file

but all these methods do not work.

When I type su root command, it will give the following output:

Screenshot of error

You should roll back to edit #4. Errors are better posted as text, because a search shot can not be searched for text.

This is the key: "The command could not be located because '/bin:/usr/bin' is not included in the PATH environment variable." You've somehow deleted or overwritten the default PATH variable. To get back, first `export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin` and then try to find where you've overridden it (could be in .bashrc or /etc/environment or /etc/profile, etc.)

It's possible you've done more damage than that, but that will get you back to being able to make calls more easily, at least.

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.
