I am unable to update my ubuntu server 14.04 using apt-get update.

Outcome is: 

W: failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/trusty/inrelease

And another error is:

/usr/local/snort/bin/snort: error while loading shared libraries: libdnet.1 : cannot open shared object

How can I solve this?

  • Was this a fresh install of 14.04 or an upgrade? Can you post the output of grep '^deb ' /etc/apt/sources.list – bain May 06 '14 at 12:13
  • Something is wrong with your sources.list - restore it by following the answer to http://askubuntu.com/questions/459542/missing-canonical-partners-and-independent-repositories-in-ubuntu-14-04 – bain May 06 '14 at 13:50
  • deb http://us.archive.ubuntu.com/ubuntu trusty main restricted deb-src http://us.archive.ubuntu.com/ubuntu trusty main restricted

    deb http://us.archive.ubuntu.com/ubuntu trusty-updates main restricted deb-src http://us.archive.ubuntu.com/ubuntu trusty-updates main restricted

    What happens if you follow the answer on http://askubuntu.com/questions/128369/sudo-apt-get-update-error-on-ubuntu-12-04 (do "select best server" in Software Sources)? And when you run apt-get update, before the "Failed to fetch" errors are there any lines that begin with "Err http://"? – bain May 06 '14 at 14:50

I just had this same issue. My company has a firewall that stopped apt-get from getting to the http sources. They still allow ftp traffic, so I was able to work around the firewall by changing all the "http" sites in sources.list to "ftp". For example, in file /etc/apt/sources.list, I changed line:

deb http://us.archive.ubuntu.com/ubuntu/ trusty-security main

to

deb ftp://us.archive.ubuntu.com/ubuntu/ trusty-security main

Now apt-get is able to fetch the files from the repositories.

You should try sudo apt-get upgrade that will run as superuser and upgrade you to 16.04 if you dont want that try sudo apt-get update to run the command as superuser thats what u usually do if your updating your current version there also could be no new updated versions but I bet there are if you want to check you can use sudo apt-get dist-upgrade to upgrade your current verison of ubuntu like 14.04 to 14.14 for expmple though ther might not be a 14.14 version of ubuntu!!! Thank you for the question!
