Computer will not update - PPA

Please post your error logs if you are having problems with updates. You can re-run the update and upgrade commands and make them record the results to text files.  If you post the text files back here it might show what is happening.

To do this, open a terminal by pressing 'Ctrl' 'Alt' and 'T' keys together.

In the terminal window, type or paste in these commands followed by return/enter each time. Answer any prompts and enter your password if asked.

Code:

sudo apt-get update | tee ~/"$(date +"%Y_%m_%d_%T")-apt-get-update.txt"

Code:

sudo apt-get upgrade | tee ~/"$(date +"%Y_%m_%d_%T")-apt-get-upgrade.txt"

Running those commands should create two files called apt-get-update.txt and apt-get-upgrade.txt in your home directory.  The filenames will be prefixed with date and time information.  You can open them to review what they contain.
Post back attaching the two files.
