In the Terminal 13.04

You can try the following since the package needs to be reinstalled . I am seeing this package installed on my system.

sudo apt-get install --reinstall libbonoboui2-0

sudo apt-get update

Frogs Hair's advice is correct, but if somehow you run into errors again, you could purge that package and afterwards try to re-install it:

sudo apt-get purge libbonoboui2-0

and then

sudo apt-get install libbonoboui2-0

I have done a brand new re-install "13.04" 64 bits. The "Terminal" functions there are no problems when doing up dates. But on booting "I am just on a single boot" computer hangs once out of three times.

this is usually the result of mixing repositories for different versions, normally upgrading to the next release without disabling added PPAs, and can usually be remedied with some combination of ppa-purge and manually removing packages with no installation candidates. the easiest remedy isbto disable extra repos in advance of a release upgrade
