I just tried to upgrade my version of PHP on Ubuntu 12.04 and now I have messed it up. First I did this:

sudo add-apt-repository ppa:ondrej/php5-oldstable

Then I did this:

sudo apt-get update

Then finally I did this:

sudo apt-get install php5

And now I am getting an error message about Sub-process /usr/bin/dpkg returned an error code (1)

What have I done wrong? How can I fix this problem? Thanks.

Here are the errors received:
