I am still trying to get my head around what you have mentioned. Have been inactive for about 3 months as far as playing with Linux, the KDE and MiniMe setups I have just worked. I was aware of the upgrade to 2011 ISOs and have only just upgraded my MiniMe, when I wondered through a few posts and noticed this one.
From my System last upgraded/updated in May 2011:
I have an interesting situation, I use AARNET mirror and for some reason if I do a major update, in terms it takes say over 30 min download, Synaptic will unlikely complete successfully. Always seems that 'peer' has terminated the connection.
I am left with having to decide to continue update anyway or not. My experience has been to look at what files, normally only a few did not come down, and how important they look and then decide to continue or not. So far I have continued and as soon as the system is ready, immediately gone back and let the update repeat once more. This works in 95% or more of cases. Really only remember as it happened very recently when upgrading my MiniMe and I continued and all appeared ok, except it seems my kernel was too old. I vaguely remembered something about problems with video card and help from Forum soon had that sorted out.
From my MiniMe system very recently fully updated:
Having updgraded I decided to have a go at installing LibreOffice last night, ran in to a problem which mainly boiled down to attrocious for me internet connection speed I think. The speed suddenly jumped right when I decided to follow the off line install procedure as the 150 MB downloaded at full speed. It was past 2 in the morning so I did not pursue if this was co-incidental, I assume it was.
During the exercise I was asked to do this "aptupgrade" so now I understand your first line, this is why I mention my 'old' system and 'new'. I will have to try an update/download and then cancel towards the end and then see what happens.
In the last post Hootiegibbon mentions the state of apt-cache however this is getting above my head.
