most of the old lowlatencys as well, so that I'm now left with
3.5.0-31-lowlatency and 3.5.0-33-lowlatency. That's what the advanced part

"apt-get upgrade" will tell you, and the packages will be kept back. (To
install kernel packages from the terminal you would need "apt-get
dist-upgrade"). To be on the safe side,  you can "--just-print"

sudo apt-get upgrade --just-print
