I have an Ubuntu 15.04 and every time I try to download something (using sudo apt-get install), it says:



Reading package lists... Done
Building dependency tree
Reading state information... Done
Package <packagename> is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package '<packagename>' has no installation candidate


I have tried "sudo apt-get update" and it said at the end:



W: Failed to fetch http://ppa.launchpad.net/irie/blender/ubuntu/dists/vivid/main/binary-amd64/Packages 404 Not Found

W: Failed to fetch http://ppa.launchpad.net/irie/blender/ubuntu/dists/vivid/main/binary-i386/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.


I have also checked whether all of the checkboxes from "Ubuntu Software" tab of the "Software and Updates" window have been selected, and tried "sudo apt-get upgrade", but none of them worked.



Also, here is my sources.list file, which seems fine:



# deb cdrom:[Ubuntu 15.04 _Vivid Vervet_ - Release amd64 (20150422)]/ vivid main restricted

Also, I know that there are other questions similar to this one, but none of the solutions worked for me.



Edit:



As I saw, many people in the comments suggested that I change the 'archives.ubuntu.com' lines in the sources.list to 'old-releases.ubuntu.com' because I have an outdated Ubuntu version. I tried that and the same message pops up when I type 'sudo apt-get update' (some index files failed to download), and when I try to install a package the same thing happens.



Some other people in the comments suggested that I upgrade to a newer Ubuntu version, which I tried also (sudo do-release-upgrade), but at the end it says:



Cannot upgrade, an upgrade from 'vivid' to 'xenial' is not supported with this tool.


I've also tried upgrading using sudo do-release upgrade -d, but then it says:



Checking for a new Ubuntu release
No new release found

    The standard 'release-upgrade' tool will jump from 14.04LTS to the next LTS version which is 16.04LTS. For non-LTS versions; your 15.04 should become 15.10, then 16.04LTS. Many people decide to just re-install rather than in your case two-jumps. (15.04 = 2015.April release; LTS releases are even.year.April only)

I fixed it by myself. I followed a bunch of people in the comments' advice by replacing 'archives.ubuntu.com' links in the sources.list file with 'old-releases.ubuntu.com' and also deleted a bunch of out of date repositories that were preventing me from executing 'sudo apt-get update'.
