I believe my internet briefly cut out while I was downloading an update and screwed something up.

When my update finished the update-notifier told me "a problem occurred when checking for updates."

I tried to show updates but the button isn't working. I have also tried to open terminal to run sudo apt-get update but terminal won't open.

Everything else seems to be working fine.

Any ideas on how to re download the update without using terminal?

EDIT: All the below suggestions haven't fixed the problem. I am going to reinstall ubuntu tonight most likely.

You can press Ctrl+Alt+F1, login to console and run there

sudo apt-get install -f
sudo apt-get update
sudo apt-get upgrade

  • I should give you an upvote :) – A.B. Jul 30 '15 at 16:51
  • This didn't work :( I still have a “Problem occurred when checking for updates” and my terminal still won't show up. – user2327814 Jul 30 '15 at 17:31
  • @user2327814 why should this not work? You have asked for a terminal. tty1 is a terminal. – A.B. Jul 30 '15 at 17:35
  • @user2327814 Can you post full error message? – Pilot6 Jul 30 '15 at 17:36
  • Sorry I should have been more clear. I was able to go into tty1, successfully run the apt-get commands, and get back out. I then restarted my computer and nothing seemed to change. I still get the “Problem occurred when checking for updates” prompt and can't open the gnome-terminal. – user2327814 Jul 30 '15 at 17:37
  • Run `sudo apt-get install --reinstall ubuntu-desktop` in tty1. – Pilot6 Jul 30 '15 at 17:38
  • @Pilot6 The full error is "A problem occurred when checking for the update" I see this error message from a red circle with a minus sign in it located in my task manager. I don't know of a more detailed way to view the error. – user2327814 Jul 30 '15 at 17:40
  • Trying to reinstall ubuntu-desktop did not fix the issue. – user2327814 Jul 30 '15 at 17:44
  • OK. Run `sudo apt-get install --reinstall gnome-terminal`. – Pilot6 Jul 30 '15 at 17:45
  • Are there any errors when you run `sudo apt-get update` in tty? – Pilot6 Jul 30 '15 at 17:45

  1. Ctrl + Alt + F7 is your home ticket
  2. Use Ctrl + Alt + F1 to switch to tty1
  3. Login and make your updates
