Hi,

I am using Ubuntu 10.04. I can not install or update anything. On my task bar there is an arrow with orange background saying "A problem occured when checking for the updates". Everything, except for updating and installing, seams to work normally.

The problem appeared when I was changing my default version of Python, by installing from source and changing symbolic link, from 2.6 which is default for Ubuntu 10.4 to 3.1, and then to 2.7.

I have read several similar threads on the forums but none of the advice there seams to resolve my problem.

sudo apt-get -f install

returns
