Ubuntu 14.04 will not update on my Dell Inspirson. I don't know what steps to take to resolve this on my own. I have already checked my system settings, software & updates and I check all sources except pre-release updates (trusty-proposed). The system updates the catch and I see updates being compiled but they always fail to download to my computer. I also tried checking the (trusty-proposed) update, with no further changes. Please help if you can.

This may be an IPv6 issue, the updates will just stall, try this to see if it helps..

Something similar to this Answer

Add -o Acquire::ForceIPv4=true when running apt-get.

If you want to make the setting persistent just create /etc/apt/apt.conf.d/99force-ipv4 and put Acquire::ForceIPv4 "true"; in it.

Running sudo apt-get update && sudo apt-get upgrade from the command line might give more clues to what's going on.

You could also try clearing the apt download directory with sudo apt-get clean and check you've adequate disk space.

  • This is what the system error reads <br/>_E:The package linux-headers-3.13.0-76 needs to be reinstalled, but I can't find an archive for it._ <br/>I just don't know exactly where to find a trust-worthy source. <br/>Any references? Feb 12, 2016 at 19:32
