Too descriptive question, please bear with me. Thank you I'm using Dell Atitude E7440, which has ubuntu 18.04. The alt+ctl+t is not opening any terminal & clicking on "File Manager"(keeps on loading near Activities bar for few seconds) as well is not opening any window. I opened VS code and from there, I am able to access my terminal. So far, I have checked if there are any broken packages which seems of no issue. I have reinstalled nautilus & it didn't help. When I try to right click on desktop & open terminal , it as well is not opening window for terminal. Strange thing after I restarted laptop ,(File Manager broke, terminal broke & Chrome asking for password out of nowhere) Please help me to open the nautilas & terminal.

I'm able to open nautilus from VS Code terminal using-

sudo nautilus

Called "net usershare info" but it failed: Failed to execute child process “net” (No such file or directory)

Within Nautilus, I see two new mounted devices on the left side (efi & the loaded drive to the laptop)enter image description here

Thank you

    It may sound weird, but go into your systems settings and reapply the language settings. And let us know if this fixed it for you. – Videonauth Feb 24 '19 at 15:51

    I did go through the language settings earlier as mentioned in one of the forums. But it didn't help :( – DazzlerJay Feb 24 '19 at 15:56
  • Did you solve this? – havakok Jul 8 '19 at 9:40

I was facing the same symptoms and resolved this. Please correct me in the comments if I am writing something wrong because I am new to OS in general.


I have changed my password and everything got back to normal

It all started when I have established a connection using noMachine from a remote PC. My guess is, that due to enabling noMachine to remember my user and password for future login I have somehow enabled the automatic login on the Ubuntu host.

As a result, each time I logged in, the system did not recognize me as an admin without typing my password for each operation. This is demonstrated by a popup massage:

Enter password to unlock your login keyring The login keyring did not get unlocked when you logged into your computer which appears on opening chrome after a reboot.

Also, you gave a hint when you stated that "I'm able to open nautilus from VS Code terminal using- sudo nautilus". I proceeded to use xterm for the same results as well as launching gnome-terminal successfully using sudo gnome-terminal from xterm.

So something is definetely wrong with explaining my self as an admin to my OS. In short, a simple password change saved the day and I am refraining from autologing in with noMachine. I am sure that all Ubuntu experts here will be able to explain what happened better than me, so go ahead and comment. I will edit this answer accordingly if needed.
