[Bio-linux-dev] Upgrade to Bio-Linux 7 (at last)

[Tim Booth]

Hi,

I've tweaked the script based on Tony's reports.  Testers can re-run the
upgrade if they like and the extra couple of packages that NX wants will
be installed.  Note that after the upgrade you now have "runurl" on the
system so you can do this in one step, rather then two, if you like:

sudo runurl http://nebc.nerc.ac.uk/downloads/bl7_only/bl_do_update_to7.sh

Details...

> This, which I didn't notice first time round, I fixed by:
>    aptitude install python-software-properties

The script now handles this properly and installs the package first

> You need to install the 'fallback' session to get NX working:
> 
>    aptitude install gnome-session-fallback
>
> I also had to install Ubuntu desktop to get NX working properly:
> 
>    aptitude install ubuntu-desktop

These are both now in the master package list

> Then remove network manager, which should not be installed on a server:
> 
> > aptitude purge network-manager network-manager-gnome network-manager-pptp network-manager-pptp-gnome

I've tweaked the script to install both the above packages with
"--no-install-recommends" so that should get NX working for everyone
while not upsetting servers with network-manager and friends.

I think that was all for now.

Cheers,

TIM
