My software center has been jammed for about 2 weeks. When i click install on updates the progress bar goes immediately halfway...and then waits for the end of the universe.
How can I troubleshoot this? I've never used Ubuntu, just assume that I'm clinically Amish.
Edit: Here's the results of running apt-get update and apt-get upgrade after following Azendale's answer:

E: Sub-process /usr/bin/dpkg returned an error code (1)3 Answers
Try opening your terminal and running sudo apt update && sudo apt upgrade. It will prompt you for your user password. You should now be able to see any errors that are occurring. You can use those to ask a more specific question regarding those errors.
You might be seeing this bug (I ran into this myself after a new install):
You can use the top command on a terminal to see if this is your problem. "appstreamcli" will show up using 100% cpu.
Quick fix is to remove the /usr/bin/appstreamcli file and then update to the newest version:
sudo rm /usr/bin/appstreamcli
sudo apt-get update
sudo apt-get install appstreamFirst, start by opening the dash:
Search for Ubuntu Software Center:
Move your mouse cursor to the top of the screen, select "Edit" and then select "Software Sources".
Go to the "Other Software" tab. Try unchecking each box to the left of each entry. (Don't worry, you can repeat this process and turn a few on at a time once you have updates working to figure out which one(s) are causing your problems and should stay off. So what we are doing here doesn't have to be permanent.)
Click close. You will likely be prompted to update the package list and/or enter your password.
After that, you should see (if you click on the
tab/icon) they package list updating:
If that does finish successfully, then you should now be able to install updates normally now!
Edit: You said you are still getting errors about signature problems. Open up the dash, search for terminal, and open it.
Put this in:
sudo apt-get update
sudo apt-get upgradeThen copy the output, edit your original question, and add the output from the terminal on the end. We'll work through it from there. A reinstall shouldn't be necessary.
Edit: Ok, it looks like there is something a little weird going on with the kernel packages. You could take the output from the terminal and make it a new question, with a title of something like "Apt update trouble with linux-headers-4.4.0-24-generic", which would make it more likely someone more knowledgeable than I will see an answer your question. But I will also try to guess what we should try next.
Can you try running this in a terminal (and again editing your question to add the output to the end):
sudo apt-get install linux-headers-4.4.0-24-generic
sudo apt-get install -fI'm not sure what order you'll have to do those in, but it doesn't hurt to do them more than once, so you can try the commands in both orders if need be.
