Problem in ubuntu 16.04 :A problem occured while checking for updates

问题

Problem:

I am currently facing a problem about the update checking error in Ubuntu 16.04. I have also included a photo.

Also after this problem terminal is not working or not opening. So I can't open the terminal as well as software updater was not working currently.

I also tried through system setting for update but still in system setting software and updates are not opening and working. What is solution for this?

回答1:

try this

sudo apt-get --reinstall install python3-minimal 

I too tried many things, but this simple thing solved my issue.

If your terminal is not responding. Then use

1. TTY terminal(Shift+Ctrl+F4/some other F1/F2/F3..etc) TO exit from TTY press Alt+left arrow till you come back to TTY3 and the next time you press it will take you back to UI.
2. In TTY terminal enter your UserID and PWD to log in and type the commands.
3. sudo apt-get update ......sudo apt-get upgrade.... and the main one: sudo apt-get --reinstall install python3-minimal and exit from TTY back to UI. That's it!!! your terminal will start working like before.

I hope it helps!!
