On googling this error it seems that a lot of people are having this issue.

apt-get upgrade hangs at 0% [waiting for headers] apt-get install apache2 hangs at 0% [waiting for headers]. Some apt-get commands are working, but only certain packages.

Any ideas? I don't think this is an issue with slow repos because I've had it up for a long while and it hasn't budged from 0%. I have edited sources.list but I removed the lines I added when this issue presented itself and it hasn't made a difference.

Any clues would be really useful.

  • askubuntu.com/questions/156650/… read the mtu related answer, might be a help – Eslam Shapsough Oct 5 '14 at 22:30
  • I have tried all the solutions above, none of them work. I even tried a reboot at the command prompt, still the same,the 0% remains stuck forever. This is a serious issue because it hampers, slows down, or even prevents the user from installing and running programs or apps. I have never seen this happen in Ubuntu 14.04. I don't think it's caused by problems of Internet connection, because whenever the problem occurs I keep checking my browser by going to different websites and I am able to surf with no problem. I think it's a bug in Ubuntu 16.04 and it needs to be fixed fast. – Plutarc Nov 28 '16 at 22:39

Try to change the server selecting update manager, definitions,downloading from, then select a server more near you. and then try again.

Edit: see this link on how to add it by editing sources.list. How can I get apt to use a mirror close to me, or choose a faster mirror?

    You edit /etc/apt/sources.list to point to a different mirror – tumbleweed Jan 12 '12 at 10:35

The easiest approach consist of following commands:

sudo apt-get clean

&

sudo apt-get update

then

sudo apt-get install <package_name>

Cheers

Let me know if it works

I had to

sudo apt-key update
sudo apt-get update

From manpages:

apt-key is used to manage the list of keys used by apt to authenticate packages. Packages which have been authenticated using these keys will be considered trusted.

  • apt-key does not magically make HTTP responses happen. – Chai T. Rex Jan 26 '18 at 20:17
  • @ChaiT.Rex It does however update the keyring which solved the problem for me. – Stiin Jan 29 '18 at 21:25
  • The keyring isn't the problem with 0% [waiting for headers]. The problem with 0% [waiting for headers] is that the HTTP connection has stalled. Retrying the command will start a new HTTP connection, which might not get stuck. That (running sudo apt-get update again) is what solved the specific problem of 0% [waiting for headers] for you. Keys are involved in the process after the HTTP connection is finished, when checking the finished downloads. – Chai T. Rex Jan 29 '18 at 21:28

If you are using a proxy server and have those settings in your user environment, try:

sudo -E apt update

to run the command as root but using your current user's environment.
