Further to my previous reply, I forgot to include two links: 1- This will explain how important it is to have SWAP and how important it is to have it twice as RAM when Physical RAM is 512MB - http://amjjawad.blogspot.com/2013/04/howto-heavy-testing.html<http://amjjawad.blogspot.ae/2013/04/howto-heavy-testing.html>
The machine I'm using is a bit stronger than yours. However, my SWAP is 1GB :) 2- This machine is far weaker and older than yours - http://ubuntuforums.org/showthread.php?t=1590614&page=16&p=11832431#post11832431 It is P2 with 64MB RAM ONLY. Believe it or not? I did update it without problems :) If that machine managed to run: sudo apt-get update without problem, your machine must be able too. Sorry, forgot to include these two links :) On Sat, Apr 13, 2013 at 10:26 PM, Ali Linx (amjjawad) <amjja...@gmail.com>wrote: > Dear Aere, > > I'm really sorry, I couldn't read each and every word because this is > indeed a very long email but I did get the idea :) > > Please, read this carefully: > > 1- When you have LESS than 1GB RAM, SWAP Partition MUST be as twice as > your RAM.
