This question already has an answer here:
I'm not versed in Linux, but my father-in-law gave me Ubuntu 10.10 on a USB, because my Hardrive had failed and I put in a new one. I ran Ubuntu from the USB for a while and decided that I would give it a try and installed it onto my brand new empty hardrive. I now see that I really need to upgrade to a newer version. I thought that I could use the Update Manager and just work my way up the version, but upgrading to 11.04 fails with the message "Failed to fetch, this may be a network problem".
I can download 12.04 and 13.04, but all I get are .iso files. What do I do with them?
Running Wubi.exe doesn't work. I've searched here and can't seem to find an answer which addresses my issue, or at least one written in a way I can understand. Please bear with my inexperience with Linux.
UPDATE: So with further research I have found this:
As a release gets old (especially if it is not a LTS release), it becomes no longer hosted at archive.ubuntu.com. However, the repository is still hosted at
So try changing your repository source to http://old-releases.ubuntu.com.
This is great, but I'm now having difficulty finding somewhere that describes "Changing your repository" for a layman. I have found these:
But I can't seem to follow how to add the "old releases" url to the repository.
