I've been hating using Windows for quite a while and I'm trying Freya as a possible substitute.

However, I can't do updates to the system.

I get a window with the warning written in the title of question. If I continue, it says sources are not trusted and after clicking to continue it does nothing. On terminal, using update command, it always shows the same things.

EDIT: I uninstalled the software updater and installed again. Tried some more times to update. I managed to update twice (~60Mb in first update and some Kb in second) and I have freya for 1 month. Nothing else showed up. The terminal always shows a long text with different things and errors (and download speeds etc):

Question of Daniel: I added ppa, I read in my websites that it would be a plus after installing freya. Ops?

PS: I was some time away, hence the late edits. I'm sorry if I'm not formatting correctly since all this is new to me

EDIT2: Thanks for the terminal tip on formatting;

"other software" tab is in "settings" inside software updater but not on "system settings". There are lots of repeated names like recommended updates three times, but each one has a different component when I click edit and the same applies to other update sources on the list. Should I keep them? I ran the commands in terminal (sudo clean, update, upgrade) and the output is similar and when I go to software updater the same updates are listed with the exception 0f 3Mb (total 67Mb) and no 0.3.1 or different things from before. I would really like to switch from Win7 to Freya but I still need to get it working (almost) perfect (e.g updates) but I'm inexperienced (I hope it's possible!!). Thanks in advance for your time

EDIT3 So I managed to do updates (partially, couldn't install each update fully due to errors) but now I get errors: boot partition low space so can't install stuff without warnings nor updates. SOmehow I now have freya 0.3.1 which wasn't mentioned in the updates' list o.o

on terminal:

Try clearing apt cache:

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

To remove duplicates from your repositories' list, go to Settings, then Software & Updates and hit the Other software tab. There, you can remove the duplicate repositories and uncheck the ones you don't want to pick updates from; if you're not concerned with elementary OS development, you can safely uncheck all the repositories containing the (Source code) label into the name. Then, try again to update, using the Software Updater utility or typing

sudo apt-get autoclean
sudo apt-get update
sudo apt-get upgrade

into the Terminal.
