Apologies if I overlooked this in the docs somewhere. Let me document something just incase it was missed.
My upgrade from 12.04 to 14.04 pauses on a package configuration. The first time I did this I found it to be
stuck on a screen saying
<Ok> to continue. It seemed unresponsive as I was unable to choose "Ok" with the tab or by way of the mouse and unable to proceed. I hacked around that the first time by guessing and killing that process. This time, I came to my senses and finally figure out that I could hit tab 3 or 4 times to select "
<Ok>" then press Enter (I did not screen shot that screen). So, this should be documented somehow, I would be concerned for anyone upgrading.
So, if you unable to select "
<Ok>" .. tab repeatedly until it gets selected then press enter.
Now I'm faced with a choice below but I don't know what the implications are. I have
gdm installed but I will go with unity. I don't see a link between Unity and lightdm.
What are the implications of choosing either?
