Hi, Flavia.

No, just get a "root" shell instead - e.g. on my laptop "beluga":

After that, you have root authority and don't need to use "sudo".

I normally access Bio-linux on terminal servers via "ssh" or "x2go" and
update them without any problems - The only time you need to access the
physical console of a Bio-Linux server is if you need to boot single
user to run diagnostics, or do a clean install. In fact, you can do a
remote install of Bio-Linux if someone boots the remote server from a
DVD or USB-stick locally for you and enables "ssh" for the 'live' user.

I recently did remote installations of Bio-Linux on some servers at the
Mario Negri Institute in Milan, from my office here in Scotland, with
help from my friend in Milan who booted their servers from a Bio-Linux
USB-stick and enabled "ssh" for the 'live' user so that I could login.

I've used this approach many times before to do remote diagnostics and
disaster recovery of Bio-Linux running on remote servers around Europe.

With an IPMI connection you can access the remote console directly, but
it is a serious security vulnerability to expose IPMI on the Internet.

Let me know how you get on?

Bye,

  Tony.
