problems updating

[stevef]

Also, it looks like you are trying to use DAFI de la Universidad de Murcia as an ubuntu download server, but there may be a problem with it.

You may need to adapt these for the Spanish equivalents.

Click 'Menu' and begin typing the word 'software' into the search box
When you see 'Software & Updates' suggested click on it.
On the 'Ubuntu Software' tab, check the 'Download from' pull down.
If it is set to 'Server for Spain', then 'dafi.inf.um.es' may be selected there - change it to a different server.
Enter your password if requested.
Then try again.
