[support] Drupal on laptop

[Roger]

Thank you to all who replied.
The problem was a missing address in the Ubuntu /etc/apt/sources.list in 
the security section.
I added the missing line then apt-get / synaptic had no problems.
It found and installed php-mysql and drupal now works well and the 
update manager now finds it so no need for command line.
Now to get a battery for the old laptop and I'm away.
Thanks again
Roger
