I lost my ssh connection to Ubuntu 10.10 server during the configuration update stage of an aptitude full-upgrade for a few month's worth of updates.

From the following ps ax list, can anyone tell me how I might reconnect to the screen which is prompting whether to keep the existing samba version, or use the distribution conf version?

Failing that, what's the safest sequence top kill these processes and start again? This time I'll remember to use screen to prevent connection loss.

Thanks,
Jeff
