I am about to do a release upgrade on a 10.04 server to 12.04. I am going to need to do this over SSH, is it advisable to do this in a byobu / screen session in case of any unforeseen disconnects? or will doing this in a screen session bring in an extra layer of improbability?
Thanks.
Okay I have learnt the hard way!, I did a release upgrade over Byobu, It all goes well until later on in the upgrade when the byoubu package itself gets upgraded and then its game over you lose the session.
I had to do a few of these upgrades so I ran up a 10.04 LTS VM and this time put byobu on hold via dpkg
# Put byobu on hold with dpkg
sudo su -
echo "byobu hold" | dpkg --set-selections
#check it is on hold
dpkg -l | grep byobu
byobu hold
exit
and ran the release upgrade again. The release upgrade honored the hold and left Byobu alone. afterwards when i was in my new 12.04 system I could release the hold
echo "byobu install" | dpkg --set-selections
and then just install the latest version of byobu
sudo apt-get update && sudo apt-get upgrade
