E: Some index files failed to download. They have been ignored, or old ones used instead.
jeggy@Jeggy-XPS:~$
Why is this happening, and how to fix it? I am running Ubuntu 14.10
This is probably just a race condition while the mirror is updated. It's also possible that you're behind a transparent proxy, maybe even without you knowing it.
Anyway, just wait a couple of hours or overnight, and try again.
If the error persists, you can change to another repository (ex. ...
us.archive.ubuntu.com
...) or remove previously downloaded index files in/var/lib/apt/lists
directory.I am having the same issue with
ru
servers.There is a bug on LaunchPad: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1394494
Current workaround is to switch to the main server:
Either you have a problem with your internet or the server is temporarely down. You can try again some other time.
You can check if you can reach the server with wget:
UPDATE: if anyone else runs into this issue, I fixed mine by replacing the contents of
/etc/apt/sources.list
with the following:... then run
sudo apt-get dist-upgrade
.I tested US servers as some say and it didn't work. Tested some Dutch servers and didn't work, there are many too ubuntu servers that don't work or are unavailable. Though Ubuntu has a option to seek for a best working and available server. Now it works.
and then select tab
Ubuntu Software
->Downloaded from
->other
->Select Best server
Now it does work
